Sorry, might not have explained properly. It isn't IE that causes the error, it is windows explorer. At least that is what I think as IE is not loaded and it seems to try and shut down windows explorer. I have done a defrag recently (couple of days ago) but might try a disk cleanup and scandisk. My hard drive makes a whining noise now and again and my system resources seem pretty low when Limewire isn't even loaded, the best I can get is about 48% and that is when I boot up. Could these factors have anything to do with the problem? Thanks for your reply anyway, much appreciated. Might help a bit.
