adding module to API stops main() from running?

So I'm working with a Solidworks macro I inherited.

If I edit the macro in SW:
under Modules, I have a Main:

Public Sub main()
FormBOM.show()
end sub

When I play my macro it shows my form.

Now I add another Module, ECN:
I then play the same macro, here's the weird part, the 2nd to last
function module ECN is run... and the Main:Main() is never called.

I remove module ECN and rerun the macro, Main() appears to be called
again -- my form appears

Can anyone imagine what i'm missing here?
Thanks,
Derek

 

"Sub Main" needs to be the last subroutine in the first module.
