I'm using windows 7 greek x64 and I use java 1.6
I go through Options->Edit Settings and I changed the font size to a much bigger one (>96).
Everything seems ok (meaning that the letters size changed). But the Options->Edit Settings-> Text tab isn't usable anymore, I click it but the program won't respond.
I tried to unistall the program and reinstall it but I still have the same trouble.
