Dialogs drifting off screen

Hello,

When working in Microstation for any significant length time (more than an hour), dialog boxes start to drift off screen.  For instance, the drop down for selecting element colors will initially open directly beneath the colors button, but over time, will open a few pixels to the right, and move further right each time I open it it.  Eventually, it drifts off screen, and locks the program because I cannot select a color or otherwise dismiss the box.  This has occurred for several different tools, including the scales dialog, wordprocessor dialog, the spellcheck dialog opened from within the word processor, etc. I have lost work several times due to having to use Ctrl-Alt-Del to close Microstation when a dialog box gets lost off screen (the lost dialog apparently block autosaving edits).

Is there any setting that can prevent this from happening, or reset where boxes open (short of restarting Microstation several times a). Is there at least a way to force the offscreen dialog to close so that I can save my work before closing and restarting?

 I am using:

"Microstation V8i (SELECTseries 4)"
