Event Handlers

In moving my code up to ACA2010 i have discovered an issue. I have code attached to the document_activate and document_endsave events. These do not fire reliably. If i have more than one vba project loaded, they do not always work. Only one project loaded will always fire them. I am hoping not to need o combine all my projects into one giant file. Is there a trick to this behavior? Has anyone else noticed this? Perhaps something else is wrong altogether.....

I've noticed this in 64-bit but can't say I've seen it with 32-bit.
