SHAppBar Message returned false when trying to find the TaskBar

Hi all,

I recently bought a laptop with Windows 7 on and have run across a small error message. The following message pops up randomly from time to time:

"SHAppBarMessage returned false when trying to find the Task Bar"

The laptop is an Acer and the error window has the title 'Greg'
From the msconfig window I can see a service referred to as Asus GRegistry, so I think it may be linked.

I am aware of some link to running VB script and this message, but I am not attempting to run anything to my knowledge.

Any help would be very much appreciated.

Thanks

Alex

P.S. My apologies if this is in the wrong forum, I didn't see a better option.
