Having just moved from Excel 2003 to 2007, one of the less welcomed changes
to me seems to be the regarding the sheet tabs. Previously, the tabs would
be coloured in much more obvious solid colours, whereas now the colouring
seem much more wishy-washy (sort of white at the top of the tab itself which
then builds up into the colour). This also affects grouping of tabs - now it
is much less obvious when you've sheets grouped, whereas in 2003 the tabs
would change colour completely to denote that they are part of a group. Now
I find myself having to redo or undo commands because either the sheet I
thought was being grouped wasn't or vice versa.

Is there any way of changing the settings so that these sheet tabs look like
more what they did in 2003? Many thanks!
