AOL sign in box position on screen changed

[silkie]

A couple of days ago, for no apparent reason, the sign-in box for my AOL email changed position on screen - normally in the top right quarter, it is now somewhat below the bottom of the screen (only about a third of the box showing) - I can scroll up to get whole form - just, so it's not serious - just irritating.  The scroll bar on the right moves correctly. I can't figure out how to correct and any suggestion will be appreciated.  I have Vista and Firefox browser.

Here I have Windows 7 and Firefox and it is on the left side the third item down.  It is very hard to control, it will dance around with the mouse. But it dos work.

Thanks for response, Geek - I have just booted up after a day's non use and, again for no reason, things are back to normal with the sign in screen.  It beats me why these odd blips occur - perhaps it was the rest that put things right.
