problems with display

My Gnotella display is very CROWDED - the font size seems to be too big for the space allotted in the program window as well as smaller windows opened within Gnotella (e.g. Config.). It's often hard to make out what exactly the text says - the bottom half of words are cut off. I tried to find some kind of a font control in the Config. tab but was unsuccessful, perhaps due to the fact that I can't read the text or buttons!

Has anyone else had this problem? If you have ANY clue what might be going on, I'd appreciate your help. Thanks in advance!
