Windows 7: Desktop stops responding.

When I close Internet Explorer 8(32bit) on Windows 7 x64, the desktop stops responding, I can't right-click, or none of the icons respond to clicking. The task bar still works ok. No error message appears. I have to log off and on again to get the desktop working normal again.



Any clues as to why this might be happening?

It could be one of many things. Here's one:

Internet Explorer 8 crashes, hangs or restarts while opening or closing tabs

The other thing you can try is uninstalling Internet Explorer 8 and reinstalling it (can be done on 7 as opposed to previous versions of Windows).

Also, scan your system with either Malwarebytes' Anti-Malware or SUPER Antispyware.

I have discovered that the problem is caused by the Adobe PDF Link Helper add-in. When I disable this Add-in using Mnage Add-ins in IE8 the problem goes away and all works normally. The Version of this Add-in is 9.3.2.163. Where do I find any updates to this add-in?
