UltraVNC

Hi,

I have the same problem as Dieter and I am also using a German keyboard layout.
I remember that it used to work in older versions but I'm not quite sure.

Thank you and regards
Arno

Normally pressing PRINT-Screen key requests a full screen update (same as selecting "Request Screen Refresh" from the system menu).

Is it possible to simply send the "print screen" / "PrtScrn" / "Druck" key to a vnc server without requesting screen update?

The same for me: windows open dialog box with Options.vnc instead of starting the viewer directly.

@Du10: For me it is a different behaviour (with viewer dated 20/11):

1. Launch viewer
2. Click Show Options (click or not Hide Options)
3. Click Connect (twice because first click only restarts viewer)
4. Error: "Your connection has been rejected."

Once (I couldn't reproduce it yet) when in ...

not any idea?
I just had the same thing again

Had this thread already for version 1.2.0.x, but have this issue again in 1.2.1.0:

I connect with viewer (1.2.1.0, Win7 x64) to server (1.2.1.0, Win8.1 x64). When I connect only one viewer (my own) is connected. Then I close the connection and (in most cases) wait for the next connection about ...

I also have this with Server and Viewer 1.2.1.0 as of January, 24.

It seems to occur not as often as before, but I again ran into this issue with 1.2.0.9 (u1)

Can't find download links for 1.2.0.9, are they already online?

- could not provoke the "connection still open after client is closed" up to now -> looks promising!

I had this issue again, sorry!

Client: 1.2.0.8 on Win7 x64
Server: 1.2.0.8 on Win8.1 x64

I got again this issue with beta 1.2.0.8 build Sep. 2

Arno

I totally agree with Skyfighter's sentences 1) and 2).

The last point (timeout) I also see a timeout at least with v1.2.0.5 and v1.2.0.6 after some time, even if neither the server nor the client are configured to any kind of sleep/standby/hibernation. Sometimes I connect and "forget" to disconnect ...

Tested again with 1.2.0.6 and w8hook64.dll active.
Again connection still open after client is closed...

Will now test without w8hook64.dll

Arno

I renamed w8hook64.dll (I'm on a Windows8.1 64 Bit System) to w8hook64_disabled.dll
Then schook64.dll is used.
(There is also a vnchook.dll in the directory ...)

During the next days now I will see if things are going better now and then I will post again.

Thanks and regards
Arno

Any ideas so far?

I regularly run into this issue and it is a little bit annoying.

When I'm able to create a new connection in this case and I see two identical IP addresses in "list all clients", the function
"Kill all clients" kills correctly the actual connection but not the old idle one ...

I'd like to ask if the log file already is under investigation.
I often have this problem and would appreciate this bug to be fixed.

@burzek, who started this post: do you still run into this bug or did you get it fixed by yourself?

So today (03/26) it happened again.
All connections have been done from client to server.

1. Last working connection: don't know the time, must have been before 14:55.
2. Connection started at about 14:56 led to a grey screen on client, so not able to use the server.
I waited some time, but screen ...

Yes, connection is initiated from viewer (Win 7 Pro x64) to server (Win 8.1 Pro x64).

And indeed it seems to be difficult to reproduce this error.
So far - since I activated logfile - the error didn't occur.

I will see and attach logfile if it will happen again.

Hi again,

in above case sometimes it is possible to connect to the server via UltraVNC again, not only with a black screen but with full access to the server.
In this case when I have a look at the taskbar icon and "list all clients", there are two entries with identical IP-address. I think one of ...

Hi,

same happens to me at least once a day.
In this case often (not always) a new connection displays only a grey or black screen, so remote PC cannot be used via VNC.

In these cases I connect to the remote PC via Remotedesktop and see two VNC Icons in the taskbar.
Then I kill uvnc service and ...

I'm running into the same situation.
VNC server is running on a Windows 8.1 x64 machine as a service.

My config is exactly the same as timo's except I have classic desktop theme and not XP.

As I mentioned in
[topic=17083][/topic]
and others mentioned in
[topic=16369][/topic]

this seems to be a general (and older) problem with Java applications (and perhaps others).

UltraVNC server 0.8.2 is running as a service and "capture alpha-blending" already is enabled.

So far I tried only ...

Tried uninstalling UltraVNC, cleaning UltraVNC directory and performing a clean install from scratch with no success.

Did anyone yet try to reproduce with a Java application such as JDownloader (http://jdownloader.org/) or JFritz (http://www.jfritz.org) running on UltraVNC server?

Hint: UltraVNC ...

Seems to be an "old" error:

Will try with your advice and newly built ultravnc.ini later.

This problem exists since a long time.
I remember this problem with Nvidia's driver since early 160ies or even older ones. Since then I tried with many versions (16x.x, 17x.x and 18x.x), so I don't think, this could be a reason.

This problem also arrived with Ultravnc 1.5.x and 1.6.x.

winvnc is in C:\Programme\UltraVNC

only one ultravnc.ini in same directory

Only one single monitor with Nvidia GF8600GT with latest driver 196.21

Having same problem with a Java application:
Jfritz version 0.7.3.10 (http://www.jfritz.org) running on vnc server machine.

With video hook driver 1.00.22 activated jfritz on vnc client only shows titlebar, minimize-, maximize- and close button. Inside the window you only can see the background, so ...
