Here's an interesting problem, I open Windows Explorer and navigate just fine, but as soon as I right click a file or folder the CPU usage jumps to 99% and stays there until I click away (effectively removing the right click menu). I noticed this on my laptop (AMD64 3200+ 512mb Ram) as the fan goes nuts at this CPU usage level, but something similar happens on my desktop machine too (shoots up to about 50% instead of 99%). This problem is a recent developement (at least on my laptop) so what could be causing this problem? And how might I go about fixing the issue? I'm about to embark on uninstalling all recently installed apps to see if that rectifies the issue, but I have a feeling it's not going to be that simple. Thanks for in advance for any suggestions.
