DraftSight shuts down

I have the latest version of Draftsight on my laptop (Dell inspiron 1525 Windows Vista).

It opens without problems, I can open drawings without problems. However, when I click in the graphics area the program shuts down. No error messages nothing, My screen goes black then a window pops up and tells me that Draftsight shut down do I want to go online and find a solution. I click yes and I end up looking at my desktop. BEFORE anyone says check your operating system and so on, I have, all other programs are operating properly.

I have been using the previous version of DraftSight with no problems.

Any suggestions??
