Help! I just moved my 2nd monitor from the right side of my iMac to the left. I changed the position in the Preferences -> Displays -> Arrangement panel, but when my screen locks from the screensaver, the password box appears in the bottom left corner of my iMac, instead of the center?? I've tried everything I can think of, rebooted without the 2nd screen attached, and searched online for a solution, but to no avail... Any thoughts on how to fix this? Is there a plist I can delete? Any help is appreciated, as this is annoying me. Cheers!!
