3.18.0 build 3397 Hedgehog 4X desktop freeze

Hi All,
Today i have given version 3.18.0 a try on a Hedgehog 4X
For some reason the touchscreen becomes unresponsive and occasionaly freezes the desktop. It is not possible to select anything from the screen. Selecting from groups is still possible thru commandline.
Pig+Open+Backspace states that the desktop is running, however restarting the desktop fixes the problem for a few minutes. I have started a fresh new show and also in that case the console seems to lock up

Reinstalling 3.17 does not give me these problems, so i assume the console is good
