Latest adventure with software

Well this one is going to be quick, but here goes. I was trying to open a large.rar file with IzArc and it froze so I took a step back fired up taskmgr and killed the service. Well needless to say it was not that easy, take a look at the screencap below.

I can't remember when the last time I had to do a manual shutdown and reboot of Windows XP. This just goes to show that more than likely it is the software built for Windows vice Windows itself that is the culprit.

How do I know you ask? Well 7zip, Winrar, Winzip, and Pkzip all worked fine.
