WebEx – Dragging/Resizing Window COMPLETELY locks up system

[gfi]

Hello, I am not sure if you guys have this problem… but here is the deal..
This is happening when hosting a WebEx session AND I am sharing an application..
If I resize/move the shared app (e.g. Internet Explorer), the computer COMPLETELY locks up! Even the mouse locks up.. .

I have to force power off and restart..
Has anybody seen this?

NOTE: This is happening with both the WebEx Java client and the WebEx ActiveX control on both IE7 and latest Firefox…

OK, I am answering my own question.. maybe it will be helpful for others..
When you resize a shared application in a WebEx session, your computer will completely lock up.

This is a Vista (Win2008 Svr) issue. There is a ‘hotfix’ available from Microsoft, but you have to go thro many hoops to get to it..

The WebEx knowledge base talks about this

Thanks for posting this response. Yours was the only explanation and an excellent one. I had to do two reboots today alone. Hopefully, this hotfix will correct the problem. I can’t thank you enough!

Just my two cents…

According to the Knowledgebase Article there, “This problem occurs because of an error in the Win32k.sys file.”

If a system driver has an error, why the heck isn’t it included in Automatic Updates? 👿
