when I run file manager from menu, and then when I move among files in a folder by using arrow-keys, preformance of my computer is really low... in task manager it shows that explorer is using up to 99% of CPU performance. but when I open a folder not choosing in menu, there's no problem. where's the problem? what should I do?

My only guess would be its waiting for something from the shell...but Im proably wrong...not that you would believe me anyway...nobody else does.

Oh, poor DeV :(

Wasnt there something to do with Windows Update causing 99%usage?

Maybe try LSuseSystemDDE "false" or something?
