LOL, I have had many of those mice!
I'm trying to recreate this Folder Tree in the left column of My Computer, but can't see how to do it. When I open My Computer it displays a list on the left on a blue background, with 3 headers, System tasks, Other Places, and Details. Then the right hand side, (the right hand pane), I have my Shared folders, Hard drives, and Removable drives, (Floppy, CD ROM, etc).
Is that what you see when you first open My Computer? If not, can you make a screen print, and post it at ImageShack and let us know the url web address?
You said you removed, (deleted?), the duplicate Windows folder, but then you said when you collapse it. Collapse what, the folder you deleted?
Somehow in one of those "my mouse has a mind of its own" moments, I managed to create a double "desktop" entry in the left side folder tree in "my computer" and now, after removing the duplicate (which said it was an empty folder) when I collapse it, it takes everything else below with it. It used to be its own entity and even after rolling the computer back, it continues. Any idea how I can make "desktop" stand on its own again with the rest of C: etc. as non attached folders? I'm running a Vista Media Center OS on an HP desktop.
