One of our users has Google Desktop installed and was using it fine.
However recently it has stopped working. Specifically, if she double-
clicks the icon on her desktop to bring up the little search dialog
box, nothing seems to happen. Right-clicking the icon in the taskbar
and going to search through the browser works fine - but double-
clicking the desktop icon to bring up the mini-search dialog doesn't
work.

What could be causing this? We have not installed or changed any
software recently as far as we know.

System is Windows XP SP2 and browser is IE 7.

Thanks,
Conor
