Please have a look at bug reports sent through the VO client bug submitter.

Have tried dowloading and installing client, plus uninstalling and reinstalling as well. Keeps crashing. I have texture precaching turned on, if that helps.

Are there some registry or .ini settings I can reset?

That's very strange. The DirectX 9 driver is crashing.

Try switching to Dx8.1 by editing the config.ini file located where you installed VO and change this line:

VideoDriver=DirectX9 GKGL driver

to:

VideoDriver=DirectX8.1 GKGL driver

and if that doesn't work then try switching to OpenGL mode:

VideoDriver=OpenGL Reference GKGL driver

If you just want to reset VO, delete the config.ini and wgaf.cfg files.

Ok, none of those settings worked, in fact X8.1 totally screwed my second monitor.

I've been using OSX so long that it never occurred to me to reboot the WinDoze box, but now that I have, it is working fine (with X9.0).

Thanks for looking into this.

AH heh. cool. I'm glad you got it to work.
