Windows XP Explorer has a 'feature' to provide a preview in the Details box on the left of the file you have selected, if itís supported. Image files, HTML pages, video clips, MP3s, etc are all previewed (even with the folder view open).
If you have a large movie clip and it either is corrupt (ie. no index from a partial download) or it uses an unsupported codec, then Explorer tries to load the whole file. This can slow your computer a lot and prevent deleting/renaming/moving/etc the file until itís finished.
Simply do the following:
- Click Start, then Run, type regsvr32 /u shmedia.dll and click "Ok".
- A window will pop up saying that the file has been unregistered successfully. (If you don't receive this window, or the window gives an error, then please post that in your reply.)
Reboot your computer and see if the problem persists.
