Webex: Black screen on Windows 7

Today I've spent a certain amount of time trying to solve a screen sharing problem with Webex on one of my laptops.
The problem was each time I shared the screen the black box appeared and a mouse on top of this.

I've tried almost everything: intalling/reinstalling different browsers, different JREs (i586, x64), reinstalling of video dirver. I performed almost all the steps I could imagine and was close to reinstalling of OS...

The problem was solved by tweaking the screen:
- Disabled 3D accelleration for desktop in NVidia Control Panel (switched to automatic)
- Changed the color depth to 16bit (was 32bit)

And that helped...

I suppose there should be an automatic switch to 16bit scheme when the sharing is performed but for some reason it doesn't work.

So before ruining the system - try this workaround
