This might have been reported, but don't see a report for B7. I've only noticed this once and can't easily produce it. Looking at the title bar, it looks like it overlaid a slightly longer title. There is a vertical bar (remains of the letter F), a bit of space, the actual window title, a bit of space, and the right-hand remains of another letter, a lower-case t, because titles end with "- SlickEdit":
