nope, but i'm guessing you might get somewhere if you delete your preferences (make a copy of them before you do though)
as for the location of the file of your preferences... not sure, but explore the maya installation directory folder thing
that's a "Ch" pronounced as a "K"
Computer skills I should have:
Maya, XSI, Photoshop, AfterEffects, Motion, Illustrator, Flash, Swift3D
