revMail fails on some Macs

[Sivakatirswami]

I'm upgrading a stack used in an application by remote collaborators. 
When they finish work on some data, the stack uploads it to our server 
here and I've added an email notification feature which grabs info 
about the upload and then emails it to me by invoking the user's 
default email client, auto inserting my email address and subject and 
body. The user then has only to click send. A further confirmation uses 
revGoURL to load the data from our server into their browser (these are 
XML files) so they can also see immediately if the upload was complete.

Now, testing here on my own mac OS X... it works fine, email is invoked 
and immediately revGoURL activates my browser...  I sent the new stack 
out to test the new function to another Mac user with OSX also 
installed, but on his machine the script uploads the data, then skips 
through the revMail as if it was not even in the script and boots his 
browser and shows the file.   i.e. the line "revMail 
tRecipient,,tSubject,tBody" fails and there is no error message and it 
does not cause any problem... it jus doesn't happen.

What exactly does the Mac need to ensure that there is an email client 
automatically will be invoked by revMail? I can't find any preference 
in OS X for "default mail app" that requires setting. No more internet 
config and apple has this bizarre requirment to set the default browser 
from within Safari, which one has to boot to say, choose Firefox... but 
I don't see any option to set a default email app that the scripting 
extensions would use. and I also don't know exactly what to test for to 
determine with other missing parts there may be... possible the GURL 
even is not handled on his machine? But I though apple script and 
events would be auto loaded by default for anyone using OSX.

I have yet to get a report from Windows users if this will work...

Note, this stack is being driven by a splash screen standalone "player" 
and I did  include the "common library" which would be required... and 
if revGoURL works, one assumes this is proof the common library is 
present.  So, it must be something else.

TIA
