hmm... so it would seem that Mail has some threshold for clicking and  
moving, before it actually starts a selection (or drag for that matter)?

Do you know if the tablet report fractional coordinates? That might  
be the difference, i.e. that TM is seeing movements of only a  
fraction of a pixel, which Mail ignores. I can try to truncate the  
coordinates.

Sorry to be blunt, but this idea strikes me as absurd ;)

a) you will be able to disable re-selection in b17 (see my other  
letter on the subject)
b) if Mail doesn't have the problem, clearly it's just a matter of  
replicating what Mail does, rather than let the user work it out by  
disabling features.
