John,
First as Fred already noted use UNC path not mapped.
I think you got me wrong. I didn't mean a dataenvironment class. A session class. At least to my experience if it's not a privatesession COM object has problems accessing the data.

define class MyClass as Session Olepublic
Datasession=2
*...
enddefine

Hanging reminds me it's trying to pop an error message but it can't have a user interface. Either check what's going on with an error routine and/or first compile to an exe so it could have a user interface.
As a trial you might modify your addition procedure intentionally to produce an error and check if that'd hang too. ie:

Answer = FirstNumber + SecondNumber + 'errorproducer'
