Draftsight 2015 x64 crashes after inserting blocks

Almost every time I insert a drawing as a block a few seconds later Draftsight will crash.

If I insert the block and immediately do a save dwg then close and reopen Draftsight and the drawing everything is fine until I insert another drawing as a block.

I am using Draftsight x64 SP1

Anyone have similar issues or am I the only one?
