Change Windows Themes --> CRash or Hand VNC Server

When a connection to a client (SmartCode Solutions ActiveX or VNC VIewer) is open, changing the windows theme from e.g. classic to standard causes the VNC Server to hang. In this case, the theme change also needs about 30 seconds to complete.

The only way to get around this is by killing the winvnc ...

Crash seen on the server

Hi, I've seen the server crashing sometimes, but I'm not able to reproduce the error. I have however enabled the log file and am posting it here. Perhaps someone can determine the cause of the problem.

Is a there a maximum monitor setting defined somewhere?
