About every 5-10 minutes, uVNC steals my window's focus. It happens on more than one PC running Windows 7 x64. Is there a setting I can change to resolve this?
I have tested other VNC programs and I can't replicate the problem.
Any assistance would be appreciated.

Re: uVNC steals window focus
I am only using the Viewer. The target PC is a Dell OptiPlex 9010 using Intel's AMT. I VNC into it to reimage it monthly.
Thanks.
Thanks.

Re: uVNC steals window focus
Can't find anything in the src (setfocus or setforground) that could cause a 5-10 min focus change.
The only thing is that when you use fullscreen mode, vnc try to put himself on the top position.
Else the local toolbar put himself on top of the fullscreen and you see the remote screen with the local toolbar.
