Office 2007 - Excel - Danish

Suddenly the standard shortcuts stopped working. ctrl-c/-v/-i/-s/-p
ctrl-shift-: and probably many more...

For instance when typing ctrl-c a pop up is saying that Excel couldn-t find
the data you are looking for.

When typing ctrl-s or ctrl-i the selection jumps til the next empty cell.

The Lotus-Compatibility is unchecked.
"Extend selection" not selected.
Scroll lock isn't on.
