I'm not sure of the right words to use, so I'll just over describe this:

On the Files screen, if you click on a file name so that is highlighted and continue holding the mouse over the filename, a white-filled box appears with the filename in it when the filename is wider than the column width.

Occasionally, this white box will not disappear when the mouse is moved away. In fact, this white box will stay on the screen even if Xolox is minimized. The only way I have found to get the white box to go away is to halt Xolox. This white box "floats" over all other windows.

I'm now using 1.41 b510, Windows XP, no service pack, 512 MB memory. I have seen this in earlier versions of Xolox, too.

Minor problem, I know. I've been generally happy with Xolox. Keep up the good work.
