Finder Bug in Move operations on Leopard:

[I Bloom]

There's a small possibility of data loss while moving files around in OSX 10.5 Leopard. It doesn't effect copy operations (i.e. drive to drive) apparently only movement (within the drive operations, from folder to folder). Probably nothing to get too excited about, because you would need to disturb the destination folder to trigger the problem but its worth knowing about if you are DITing on a Mac, because if you did do that, all your data would be cut off and essentially deleted.

I just installed the update...now my hard drive won't boot...not even recognized by the computer. Ugh!
