chasing the "edit card details" window

~~~Is anyone else having an issue when they go in to edit card details, such as edition, and the pop up box just goes nuts & expands indefinitely?  whenever I enter a cards details, the edit & cancel buttons just start sliding down the screen as teh box expands forever & right off the screen...so I have to try to chase the button & click it quick while its moving. 

I'm on a Wondows 7 machine running IE9 as a browser.  I know there were other issues with IE9 & am wondering if this isn't just another of those incidents.
