The thing is that depending on the context "me" is evaluated  
differently, so all the different tests etc. don't really count for  
much, except that they evaluate ok in *that* context or they don't.  
The tests you did are just red herrings since they change the context  
of how "me" is evaluated. The only way to *know* is *if* you have  
access to the source code *OR* of there were documentation stating  
exactly what is *supposed* to happen.

I'm not sure if it has been filed or not, the idea of posting it here  
was to get some feedback on exactly what the bug was (and thereby be  
able to file it correctly) and get the "officical" work around. The  
sharedText property just causes more headaches.

All the Best
