That is not the normal behavior of F2 in any version of Excel.
Perhaps you have a macro attached to that key. You can restore F2
to its default action with the following macro:

Sub AAA()
Application.OnKey "{F2}"
End Sub

I recently upgraded from Excel 2000 to Excel 2003. Now, when I
press F2 to
edit a cell, the background of the cell turns blue, and
pressing enter will
insert a new line within the cell instead of submitting the
change. This is
very different from Excel 2000, and it is causing some
frustrations for me.

I noticed that if I hit F2 twice, the background of the cell
turns yellow,
and I can edit it like in 2000.

Hitting F2 a third time returns it to blue.

There must be an option to have it use the "yellow mode" by
default instead
of the "blue mode". But I can find absolutely *nothing* in any
documentation
about what these different modes actually mean. Could anyone
fill me in?

Please do not suggest that I simply press F2 twice every time I
want to edit
a cell. :)

Thanks,
DJustin
