Do you play in full screen or windowed? What is your OS version and archetype? Does this happen in the 64bit version?
This especially. Try running in full-screen to see if that fixes it. We think the issue is with the Windows Forms portion of our application affecting some users who are not running in full-screen mode. Possibly more so if there are multiple monitors.
There is a beta version we have in the works to remove the dependence on a Windows Form GUI all together, as well as provide some more debug tools. PM me if you would like to try it. (It's not ready for wide scale distribution yet)
I play on fullscreen. Win 7 x64 Pro though I play on x86 client so I can see who's talking in Mumble.
This was happening in the x64 client as well but I resolved the issue. Turns out I was missing some of the newest C++ runtime updates which RTST did not like :facepalm:
Sorry to waste your time and keep up the great work.
