This problem has resurfaced on a Win7-64bit pc with an Nvidia Quadro 4000 video card, using Nvidia driver v320.00, running MicroStation ss3 v8.11.9.357. Specifically, the display may freeze, then black-out, then recover with an error message, as previously reported. For us, this error was repeatable, and occured when zooming in and out while in the middle of the place dimension command.
The workaround reported in http://communities.bentley.com/products/microstation/w/microstation__wiki/4172.aspx does seem to cure the blackout problem.
This problem was previously reported, and was supposedly fixed with Nvidia driver version 307.32 and/or 307.45, depending on the version of video card, according to bentley.
I will download and install that version of driver to see if it cures the problem as previously reported.
We had similar problems several months ago after upgrading to SS3 ver 08.11.09.357
I noticed was that some users weren’t experiencing the same problems as others.
Two users plus myself were having MicroStation crashing frequently along with the black screen recovering message.
I haven’t checked exactly which version of NVIDIA driver all the pcs are using but my pc is running NVIDIA driver version 320.00
PCs have a Quadro 600 graphics card.
Operating System is Windows 7 Enterprise SP1 64bit
One difference the pcs had was the mouse they were using and as a consequence the driver.
On my pc I’m using an Intellimouse Optical with the latest driver.
Having looked at a number of previous posts including the link in your post on the issue and also looking at the NVIDIA forums I did the following;
Set the config variable
QV_D3DVERSION=9
This will force the graphics to use DirectX 9
Make sure any users having problems change the Personalisation Theme from Aero themes to Windows 7 Basic and change mouse pointers scheme from Aero to none.
This has helped the situation a lot but there are still minor display issues such as screen not drawing properly on occasion and the user needing to refresh the screen. The three users (including myself) who were having MicroStation crashing and the black screen driver recovering message have not reported any of those problems since implementing the above changes.
