Problem with deselecting cells

[Guest]

Hi,

When I am using Excel, suddenly the pointr starts selecting all cells, and
will not quit. This makes the entire worksheet to move twards the pointer,
and by this I'll end up at the last cells, possible in the worksheet,
selected.

My only way to get nack is to restart the computer, since the menues don't
work either.
Is this known? What to do?

Thanks/

Try this when it happens:

Hold the the CNTRL key and select some cell
