We are using UltraVNC for some time now (1.2.0.5) 64bit and in windows 7 everything runs smoothly for some years now! Thank you.
However, we are rolling out windows 8.1 and facing a problem that the connection is lost when running a exe with admin privilleges on the remote PC. It also takes more time before the remote screen is visible.
Uvnc is installed as a service.
What can be the reason of this problem? I installed the latest version as a test but this does not help.
Thank you for any help solving this issue!
