Draftsight crashing when opening and closing files

 

I have draftsight 1.4 installed

Windows 7 64bit service pack 1

Nvidia Quaddro NVS 295 with latest drivers

Latest Broadcom network drivers installed

 

When opening DWG files sometimes draftsight crashes with error and wants to close

 

When clicking the close option from the file menu very frequently(maybe 4 out of 10 times) draftsight will lock and and not respond. Then have to close with task manager.

 

The files are stored on a network drive
