Why is my Draftsight freezing when placing a dimension?

I am running 32 bit Windows XP with Draftsight Ver. 11.2.802 and the majority of my files are accessed via the network from on a file server.  When I try to add dimensions, the Draftsight will often freeze at the point of placing the dimension.  Everything runs fine while selecting the points I am trying to dimension between but after I click on the location I want it to be displayed, I usually have to exit the program because it will not come back out of it.  Has anyone else experienced this and if so, is there a fix?  It's really frustrating!
