I wouldn't see xl2003 having any trouble with that command.

xl2003 should be able to run anything you develop in xl2000.

I am not aware of any incompatibility in what is developed in xl2000 and
then run in xl2003. If there is, it isn't in any commonly used functions,
methods or properties.

After the error, try going into the vbe into tools=References and see
if
have a reference marked as MISSING. If so, you need to resolve the
reference.

This is just a guess of course, since the information you provided is
extremely limited.

Hi to all (and Tom especially),

I try to open the workbook window fully,
adjusting it to the maximum usable space.

Sorry for´providing "extremely limited" information.
here is the code:

With ActiveWindow
.Left = 1
.Top = 1
.Height = Application.UsableHeight
.Width = Application.UsableWidth
End With

Each of the 4 lines between With.. and .. End
are producing an error. That is what the customer says.
He has XL 2003. I have XL 97, 2000, 2002 only.
If I deliver the application to the customer after it
runs errorfree in my environment*s* - can he
then have a Reference not resolved still?

I am not so deep in the vbe, but XL 2003 should
be downward compatible to Excel 2000, which
is the platform that I use for development.
