Crashes on File Open

DraftSight crashes when the file open dialog box is on the screen--as soon as I use the mouse to move over a file I want to open Draftsight vanishes--no questions asked.  This has happened with R3.1 and is still happening with R3.2.  I am running Win 7, 64-bit.  I have Solidworks 2013 on the same computer and it runs flawlessly.  I am also running EPDM on this computer.
