random veiwports turn off as i turn others on

[mvrcad]

HI All

AutoCAD isnt being nice to me lately

another hassle i have is the viewports randomly turn off ( they dont show anything)

and when i turn those ones on, others turn off.

I suspect its a video card issue causing some sort of degredation, however i thought i'd see what you guys think.

Cheers

Marcus

 

 

 

hi all, i dont know how to change the topic to "solved"

however a collegue told me to enter MAXACTVP at the command line

the value was 16, i was told to set it to 64 ( i had 21 viewports )

and they all came on.

cheers
