Access 2003 and 2007 coexisting

I've just installed Office 2007 and am coming to terms with the
drastically different menu structure!

One problem I have is alternating between different version of Office
applications and getting that bl...dy paint in the ...."wait while
Office is configured " message.

There is a registry fix for Word I found at
http://word2007bible.herbtyson.com/2007/04/15/word-2007-and-word-2003-coexisting/

So I'm wondering if there is an equivalent registry fix for access?

There is no equivalent registry setting for HKEY_CURRENT_USER\Software
\Microsoft\Office\11.0\Word\Options
on my pc, can I just create one?

thanks
