Question: Maple 17 doesn't recognise certain keys on my keyboard.

I upgraded to Maple 17 from Maple 16 today and I noticed that all of the sudden I can not enter the } symbol anymore although the { symbol works just fine. (I have an azerty keyboard so those keys are AltGr+0/ctrl+shift+0 and AltGr+9/ctrl+shift+0 respectively). My solution right now is to enter the symbol each time via the fences panel, but  since it's a commonly used key this isn't really optimal. 
Does anybody know what causes this and how I can fix this?
