Odd behaviour from revMail, why?

[Peter Alcibiades]

I got the attached from the dictionary, cut and pasted it, and only changed it 
to make Field1 a real reference to a real field on the test card.  When I use 
it, the first thing that happens is Firefox opens.  Then Kmail opens.  It 
shows help at example.com as the address, but nothing else is put into either 
subject or body.

I was expecting to see Help! appear in the subject, and the contents of Field1 
to appear in the body, and for only Kmail to open.  Isn't this what is 
supposed to happen?  Putting in a literal string in place of field has no 
effect either.

Does revMail do this on Mac or XP?
