Windowed issue

[Arterian]

I always have run in windowed mode, and the screen just about perfectly fits in my monitor. Something happened today and I froze, when I came back now the Windows taskbar encroaches on my screen at the bottom so I can't see part of my chat window. When I try to manually pull the monitor up and move the top bar that says "EverQuest" up, it rubberbands back down again.

Any ideas how to fix this?
