OK. I've looked at this a bit. blagCanyon, the main BLAG theme, was originally based on Grand Canyon.
One quick test is to just right-click on the desktop, go do "Disks" and see what is checked. Some themes have it wrong, some right, some nothing...
Themes that have checks when should be unchecked
Themes that are just blank
Themes that have it right

This bug was reported to redhat/fedora forever ago. I let them know it's present in Fedora Core 2 (just checked it):
https://bugzilla.redhat.com/bugzilla/sh ... ?id=110167
For that matter, it was in redhat 9 even:
https://bugzilla.redhat.com/bugzilla/sh ... i?id=89467
I think that lots of programs used to do their checkboxes in a different method so it wasn't seen as much...
The fix is quite easy. I want to rebuild blagCanyon and roll in a couple other minor changes too (waiting on a couple icons). When that's done I'll upload the new blagCanyon for apt-getting. If it really drives you nuts you can just make the minor change listed in bugzilla to your file (/usr/share/themes/blagCanyon is the dir).
