Using ‘22 DS Enterprise. Issues. (1) When drawing and using "pan" the screen will go black & then shut down. This happens in all drawings. I have a HP Z2 SSF G4 Workstation. HP checked it and is working properly. Have a good NIVDIA GC and HP recently replaced GC incase it had issues. Have 32 gb RAM. Still get a black screen. No one seems to be able to fix it. (2) Have a selection issue. One item is when I try to erase several items, I can only select one item at the time instead of several items. Does anyone have a suggestions? Used DS for 3+ yrs.
