Honestly, I'm not sure where to post this. I am running Windows 7 Enterprise 64-bit. I keep my taskbar on the top. I have a few programs that don't seem to know that my task bar is on top (2 that I know of - iTunes 10.4 64bit and Freemake). So when I maximize them there is a gap on the bottom where it thinks the taskbar is and the top of the window is underneath my taskbar. I'm sure there are other programs that do this. I'm not sure why it is doing this?
