I only have it display the chosen (current) icon for that folder on purpose. 1) If the icon is an ICO file, then it is copied to the folder hidden and renamed so the folder can be "portable". The icon should show on other systems if it is on an external drive/usb stick. If it is an icon resource (DLL, ICL, or EXE) it will load the icons from that file and show the current one. 2) If it is an ICO and selected from a folder if icons, I didn't want it to have to load the whole folder again. 3) was a lot easier to do it this way as there is a bug that I am still unable to fix. It just crashes CMF when it loads... not sure why.

Not sure about the double-click, but what I am doing is allowing 2 views. The original icon view then a small icon view that just shows a small 16x16 icon. The icons load much faster in this view. I'll post a screenshot a little later.

1) In the beginning, does that folder open on it's own after closing CMF?
2) In shell23.dll there are some blank icons, that is the way MS made it. Not sure why, but that has been that way for a while. It's even that way in Windows 7.
3) Sometimes the icon doesn't change right away, not much I can do about that. It will show that is has been changed on CMF though right away. If you log off and back on it (or reboot) should be changed.
4) I see that it is going a little slow on your system. I don't think I can do anything about that either, but I'll see if I can speed it up. Getting and loading the icons can be slow.

Did I miss anything?

Do you mean the Color My Folder location in the My Documents folder... for custom icons?
