When you start UltraVNC Server as normal user you can't control any applications started with run as admin.

To be able to control that program:
- UltraVNC Server (winvnc.exe) needs to be started with runas admin
OR
- UltraVNC Server needs to be running as service

Viewer config files are under review

Fixing: listen doesn't load settings
options.vnc and custom.vnc
Adding label that show default options.vnc location and an extra option to use only the default (options.vnc) file.
This will make configuration simpler, the overwrite by the custom file make it ...

@lwc: Remove dev: Will do, just spending all my time on tracing bug reports.

@yan487: 8 colors:
If you set 8 colors and save and connect to a server.
Close viewer
Open viewer and select same host
Are the 8 colors set or is the value lost?

Thanks

Can you also provide the UltraVNC Viewer display settings?
There are a lot of options.

What do you want 2x 2K displayed on 2x HD resized or with scrollbars?
Are you using the DDEngine, should be indicated by the Viewer?

Thanks
Rudi

@wojtek: "AutoAcceptIncoming = 1" is still the correct parameter, just tested.
This can be set via Viewer -> Options -> Security

Server need to be SC or a full server started with -sc_prompt and the viewer need to have "AutoAcceptIncoming = 1" set to show this box

@Jojo67: %AppData%\UltraVNC -> Settings per server
options.vnc -> Same vncviewer.exe folder

packagefactory : That part has been refactored to make it look like how it's implemented in the other VNC flavors.
It was not possible to keep it backward compatible.
QuerySetting 2 and 4 is now just off/on.

Please take a look at the graphic interface, all combinations are possible and you also ...
