'close group' options greyed out
 

Upon opening multiple instances of excel xp\2003, the usual button appears on
the toolbar at the bottom of the screen with a number indicating how many
instances I have open. When I right click this button all options to 'Close
Group', 'Minimize Group', 'Tile Vertically', 'Tile Horizontally' + 'Cascade'
are greyed out.

This occurs only with Excel and occurs with all user if this version. I have
scoured the web and found masses of people with the same issue,
unsurprisingly no answers.

This issue has been doing the rounds for a while, does any0ne have any
solutions or at least shed some light on it?

thanks
