Well I've never seen anything like that with the Revit 2011
ribbon, everything about that release is very stable. And
I assume you have update 2 installed for that, If you don't
then go to Revit support and get it.
Graphics cards for Revit have just about everything to do
with converting 2D to 3D. I don't think the card has anything
to do with that ribbon anomaly you are showing us. But who
knows.
When you start up Revit 2011 it displays a dialog telling
you what card you have and whether or not it's been
certified for Revit 2011. But if you checked "Don't show
me this again", or whatever it says, then you won't see
it again. I always wondered how to get it to come back
after I told it to go away, but I didn't really look for it.
I go to http://autodesk.com/us/revit/revit_graphics_hardware_-_graphics_hardware_list_final.html and see all the cards
that are certified for Revit 2011.
But you can use a LOT of cards that are not on that list
that work just fine too.
But like I say, I've never seen or heard of the Revit 2011
ribbon doing anything like that. And if that ever happened
to me, the first thing I would do is go to Add/Remove
programs and re-install the program.
I know this isn't a lot of help, but that's all I know..
