[Dx4win] Odd Dialog Box issue

[David M. Monfried]

A new, very odd problem has developed with my "Save As" and "Open" dialog
boxes (using DX4WIN 7.02.15, WinXP SP2, all updates):

When I select File/Save As File/Open, then click the down arrow in the "Save
in" or "Open log file" dialog box, the drop-down selections disappear after
about a tenth of a second...and the current selection reappears. 

I've tried the Save As and Open functions in MS Word 2003 and there is no
similar issue. And I've tried System Restore, going back about a month. No
joy.

I'd very much appreciate any help in resolving this bothersome issue.

Thank you.
