Hi, any help would be appreciated.  I am using thefreeedrawings viewer.  I open a drawing file and see the imagefora split second then the screen goes black.  I thinkthedrawing is still there because the program will showtextdescribing components of the drawing.  A couple of timesthescreen was all grey instead of black.

I am running windows vista home premium

Thanks
