Whenever I'm clicking ctrl and arrow keys together, when it's not my turn the Playroom generates quite a funny sound sequence similar to the one when the client is starting but monophonic and the program quits with a fatal error. Not sure why this is but the melody before it crashes is lovely. :)
Nevertheless I hope it can be fixed.
Tested with Farkle. Will do more testing later.
Best regards

I'm sorry but am unable to reproduce it... any additionnal clue can be useful

I've done another test.
I created a free table and simply clicked ctrl+down after it got created. There were no other people in it, nothing was happening and I managed to crash it that way. It must be performed while there are no menu items on the screen so nothing that can be selected with arrow keys.
If the Playroom provides any additional crash reports I can upload those as well.

Bug found. Thank you very much, it was a nasty one. The next mandatory update of the client will contain the fix.
