Listener Hangs When Using SC

Post by tom_glebas »

I was able to get the standard VNC server and listener working, but when I tried to get SC working, it runs and says it connects, but on the listener machine, I only get a thin horizontal line at the top of the screen and the taskbar icon is hung. If the listener New Connection dialog is open, it will freeze (Program Not Responding).

Any help on why the listener seems to hang while using SC will be greatly appreciated.

I'm using 1.0.6.4 of the listener.

Does the connection use DSMPlugin?

Yes. I created an rc4.key file and installed it on both test machines and it worked in server/listener mode. I copied this rc4 file into the .zip file when creating the SC. I double checked and compared the files to make sure I didn't copy the wrong file by accident.

You may fall into the problem of using different (incompatible) version of DSMPlugin between SC.exe & Viewer.

See following thread for detail.
