All I can think of is to make sure they are saved as .BMP and not something else or that they are 256 colors.
Just guessing though.  
Vista?  I haven't a clue.

There all .bmp files.  Heck I even tried to add one as a .gif file to see if that would work because the CFS and CFS2&3 would accept either one.  The screwy thing is not that they don't work (lots of things can cause that), but the darn program doesn't even see any changes I make to the folder.  That's why I'm thinking it's hiding the info somewhere else.  Found some files under the Users area, but no bmp's are showing up in there.
I have a dive bombing sight, and a couple of fighter sights, I'd like to use, but game won't find them.
Anyone else have any ideas?
Thanks,
