I have a number of sheets so that the tabs are presentet in two rows.
When I open the file using the IE or Firefox I can just see the upper row. Changing a sheet, I can see the second row up to the moment the sheet is loaded completely. So it is impossible to choose the tabs of the second row.
Any idea? First idea was, that a dark-blue object in the head of the sheet lies over the tab. But why is it presented right in a different browser?
