Crashes on file dialog box

Hi,

I'm having continual crashes with Draftsight V1R5 x64 when opening a file dialog box, typically  "File Open" or "Save As".  It's about a 50:50 coin toss if Draftsight will crash when accessing either of these commands.

I'm running Windows 7 x 64 with all the current service packs and patches. The only unusual thing about my hardware is Dual graphics cards and 4 monitors. They are a Quadro 2000 and a FX 3700 running Solidworks certified drivers (331.82)

Does anyone have some suggestions on things to try?

 

Cheers

Craig
