Lock-up on create folder

When I want to save a new SolidWorks part and click the create new folder icon at the top of the save dialog box, SolidWorks immediately locks up and I have to go to Task Manager to shut it down.  It's not a big deal, I just need to remember not to create new folders from the dialog box, but I am curious if it has happened to anyone else or if I'm just lucky.  I am using SW2010 SP 1, 64 bit.SolidworksGeneral
