Raise all grouped windows on Windows 7 taskbar

Here's something I've found that does what I need, not one click, but not too bad.

Hold down ctrl and click on a group - each time you do one of the windows will be restored in turn in its original position and brought to focus on top. After sufficient clicks all windows in the group will be on top.

Clicking more times than there are windows is harmless as the windows remain on top, you only change which exact window has the focus.

I hope this is of some use to others.

Shift+right-click to get options such as cascading the windows or stacking them. It won't restore their original positions, but it will get them all open on the screen.
