Hello Paul,

I did the registry patch again on a clean system and checked twice if I made a mistake. On this system only office 2010 is installed so I can’t install the mentioned hotfix for office 2007 (although I tried anyway ;-))

The registry patch is done in the Office 2010 - HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\W ord\Options registry subkey.

I still can’t see any difference in behaviour with our without the registry patch. Only when I open the Excel file manually in advance it works fast.
