Alphanumeric keyboard input not working in editor pane

[GoogleCodeExporter]

I installed MiniBuilder on Peppermint Linux and for some reason I can't type 
anything in the editor window.  I can BACKSPACE, TAB, PG UP and DOWN, but I 
can't actually type anything in.  All the other places for inputting text work 
fine. Tried some different keyboard layouts, but it was all the same. 
Everything else seems to work, building etc.

Using newest AIR and Minibuilder.
