lost: all folders option

I've just been using w7 a couple of days. Been using windows for years and years, and one of the 1st things I do is to change the view files/folders option to full details, see system & hidden files, etc. And then click the apply to all folders choice. Everything's fine. Then, not particularly liking the look of the w7 COMPUTER file manager, I dl Xplorer2 for a try. After installing, looking at it for a bit, I go back to COMPUTER to find all my choices for file viewing reset and when I try to change them back again, the set to all folders button is grayed out. I also went to the control panel to access file/folder view but there still no luck getting things back. Is this some sort of registry trick? What's going on?

Jonathan, thank you. Been struggling with the software for my new computer, setting up dual booting with 7 & XP, moving zillions of old files, etc. I emailed Xexplorer2 and he said I must have checked the replace Computer with Xexplorer2. I don't think I did, but I'm working on solving the problem. (It's in the cue with all the other issues.) I must say, I really prefer the XP file manager, the clearer & cleaner look, its usability, especially the "copy/move to folder option." Where would I bb MS with my thoughts?
