I have a strange issue, which feels like it is a simple fix but cannot seem to get there. I am rather new to Linux. Nonetheless, my problem is that from my machine I sometimes run a virtual windows environment. I do not mean dual boot - from my Linux instance, I launch a Citrix supported remote desktop, kind of like oracle virtual box that kind of thing. The problem is that whenever I hit the caps lock key with the virtual desktop open, it immediately closes it again! I tried to run through the system shortcuts to see if there are any conflicts, but cannot find anything. Does anyone have any tips on how to solve this?

Cheers!
