Win 7 V3 Draftsight Crashing during "dimensioning"

Have been using Draftsight for years.  Great program!  Just started having this problem within the last week:  Windows 7 32bit, running V3.  When ever I try doing ANY dimensioning.  Window pops up "The program must close".

Tried uninstalling/reinstalling several times and deleting subsequent files.

Also tried unchecking "enable relative dimensions"

Otherwise solid performing Dell Latitude Windows 7 Enterprise laptop.

File opens on other computers:/

Thanks in advance!!
