I just ran into this issue now using excel 2007 and don't recall it being an issue with 2003. I have a protected worksheet and when I tab over a few cells and hit enter it takes me down one cell rather than to one cell down but in the same column as before. i.e. Before in 2003 if I started in A1 and tabbed over three times and was in D1, then hit enter, it would take me to A2. Now in 2007 if the worksheet is protected it will take me to D2 instead. Any suggestions?
