But surely what Chris is reporting is just the correct behaviour and not the result of sticky keys etc.
Ctrl-Alt-Tab is still displayed in Excel as the shortcut for increase indent but Ctrl-Alt-Tab is also the Win7 shortcut for a persistent version of the well-established Alt-Tab window switching shortcut.
What Chris is saying is that Win7 takes charge of this key combination [as you would expect - Win7 gets a higher priority than Excel] and he's asking if there is a way of disabling this behaviour. I think the answer is no but you might know better.
