excel 2003 screenupdating problem

[Softedge]

I have a macro I am running that was written on my Excel 2003 machine. The macro will not allow me to select a cell after I scroll the worksheet. If I select the cell without scrolling the sheet it allows the cell selection.

I have tried the same macro on my laptop that is running Excel 2007 and it works both ways.

I have Activesheet.UnProtect set and Application.Screenudating = True set. The macro works on my laptop.

Is there a global setting in Excel that disables screenupdating that my macro is not overriding? What could be causing the problem?

All help would be appreciated. This one is baffling me.

Thanks,
Softedge
