Keyclone mini windows logging in slower than normal

Hey i've noticed this recently and started messing around to figure out whats goin on.

when i launch my keyclone on this pc (my 3 dps chars pc) i run the command to launch the 3 wow's (ALL 3 from different wow folders) they all pop up at 800x600, then take a few seconds and resize and go to their corners (Top left, top right, bottom left) @ 840x512 each (full screen 1680x1050)

ok, so i type in the password and click "login" and it just sits there, the "connecting" thing doesn't show up at all it jsut sits there for a good 10-30 seconds and then finally logs in to the character screen. all 3 of them do it, but when i launch them without keyclone or from my main folder (full screen windowed mode) it dosen't do this. and neither of my other 2 pc's do this either. its not terribly annoying but just confuses me why it does it. anyone know why?
