We have some pc's with windows 7 x64 on it.
For some kind of reason design review crashes more often on those pc's, you have to think about 5 - 6 times a day. I notice that if you open some models they use already up to 600Mb memory, after working a while with those models I have seen them using more than 2Gb of memory.
After working a while (most with the orbit tool) the screen turns blank, and design review gets stuck, only thing you can do is end the process from the taskmanager.
the specs of the desktop pc's are as follow:
Dell Optiplex 990
Intel Core i5 3.10GHz
8 Gb memory
Ati Radeon 5450 video card.
We are using Design Review 2012.
Ok, I think we have found the solution by our selfs.
It seems that not every drawing gives problems, but just a few. Also other stations had the same problems with these drawings, so the problem could not be related to the pc. It looks like the problem is in the dwf file itself. Making a new dwf file at our drawing department was the solution.
