What does this Mean? 

Is this Reported to Draftsight automatically?

What do i have to do to resolve this?

cause open 2 or more drawings at the same time then try to close one drawing 

Draftsight System Hangs 

I downloaded the latest graphics drivers , Still the same Problem

I reinstalled the Draftsight Program V1R1.2 Still the same Problem

Any Ideas?

Cheers

Do I have to buy the Product to make it work or is the free one limited in some way?
