Autofilter locks up sheet!

Anybody seen this?

Autofilter is turned on in a weekly spreadsheet that I receive. Functionality to move around by arrows or page up/down works until I select something out of an autofilter drop down. Screen locks in place. Can't arrow down or up (but can go left/right). Page up/down is broke also.

If I exit and re-enter it works until I filter. Scroll lock does nothing.


Any solutions?

TIA!
