Orientation problem since update

Since the last update I have had several occasions where the orientation of the screen is wrong. Tonight the email screen was upside down and a couple times the screen was not locked, but would not change when I held the iPad a different way.
I could not get it to change unless I rebooted the iPad.

Anyone else have orientation issues since the update?

 

Yes. Tonight it did it again. The email screen orientation froze up and wouldn't change when I rotated the iPad.
Even if I closed email and then reopened it, the orientation was stuck. Only after I rebooted iPad did it work correctly.
