Folder preview not showing solution (hopefully).

I'm not sure if any solutions to this were ever found (I couldn't find any), but I think I have one.

My problem: In my Music folder I had all of my music organized by artist. However, the folder preview would only show on a few of them and the rest remained blank. I searched everywhere and couldn't find an answer. I tried clearing the cache, customizing the picture (which I still can't get to work). Nothing. So, I looked at the ones that were showing, more specifically the desktop.ini's in them. Here's the text on the .ini's with the missing preview:

[.ShellClassInfo]
IconFile=%SystemDrive%\Icons\Fol_Clos.ico
IconIndex=0

And the one's showing:

[{BE098140-A513-11D0-A3A4-00C04FD706EC}]
iconarea_image=C:\Folder Backgrounds\Dylan.jpg
iconarea_text=0x00FFFFFF

The one's showing are .ini's that I made in XP to show a background for the particular folder. Apparently, putting this .ini into one that doesn't show causes it to show. (Note: The particular image (e.g. Dylan.jpg) doesn't seem to matter. The directory shown above doesn't even exist on my computer anymore)

I have no idea why this worked or what it means (I found out how to do the folder background tweak on some site), but hopefully this will help someone.

P.S. I apologize if this is on the wrong board. Wasn't sure where else it could go.
