Right, this is driving me crazy, I accidently lent my hand on the keyboard earlier and now some of my programs have doubled in size. For instance, programs like media player are fine, correct font, correct size. Other programs like Nero Smartstart have doubled in size, fonts and all, I don't know how I did it but I need to get it sorted out!! Here are my specs in case needed. Also I have checked fonts and they are set to normal size.
768MB DDR2100 Ram
128MB Radeon 9600
