A keyboard related problem


I’m having an annoying keyboard-related problem (I have a Croatian qwertz keyboard). While trying to type [ or { (ALT GR plus F or B, respectively) in Cern Root command line, a beeping sound appears (I suppose it’s the motherboard) and nothing happens. Similar problem occurs when I try to copy or paste (it seems that any ALT GR or CTRL combination is disabled). I’ve already tried browsing through the forum but to no success.

Thank you in advance


Which OS? Which ROOT version?
