My copy of Textpad on Windows XP has started acting up where it will not let other applications, programs or windows be in front or go on top of it.
So if I'm using TextPad and I Alt + Tab to Firefox then TextPad's bar goes dim like it knows its not the "top window" but Firefox isn't placed on top of TextPad.
I've tried uninstalling and reinstalling TextPad but that didn't seem to help.
