Losing control of cursor

Post by ticotexas »

I'm using the latest 1.0.8.2 version. I have Vista at home and XP at the office. The VNC server is running on Vista. The VNC viewer is on XP. Things work great normally, but when I tried running Windows Disk Cleanup, then I no longer have control of the cursor. This also happened once before when I tried running a disk defragmenting software. I could not control the cursor until I got home to the machine and everything was fine. Once I exited the defragmenting software or disk cleanup windows, VNC could work normally again. I originally thought it was some fluke specific to the defragmenting software and since then I avoided using it through VNC. When this happens, I can still see the screen, windows, cursor, etc. but cannot move it or do anything. Has anyone else run into this behavior? Is there any setting I can change to avoid it? Is it something unique to Vista maybe? (The problem does not occur when XP is the server and Vista is the viewer.) Thanks in advance for your help.

No, haven't heard of that. Did you try refreshing? Disconnecting and reconnecting your viewer? Changing video modes before starting the culprit programs?

You said you can't "do anything" when this happens. Does that mean you can't use the KEYBOARD either? Can you type anything? What if you generate the Windows key, or Ctrl-Esc, or Ctrl-Alt-Del via UltraVNC? How about Alt-Spacebar for getting a window's menu?

If the answer to that is no, then it's a lot worse than "losing control of cursor"; you've lost control of both keyboard and mouse....

This isn't any help, but I'm just trying to precisely identify your problem....

Disk Cleanup prompts UAC, you must install the VNC server as a service or run it as administrator. This is typical behavior, UAC security blocks the VNC server program from interacting with a privileged program.

Actually, you're right...it is worse. I can't use the keyboard or special keys.
