It hangs because -w will make "$DIALOG" stall until an action is  
performed in the window, but since you run it from TM, the main  
thread (in TM) will wait for your command to finish, and thus block  
the UI.

Try instead run it in a shell -- in practice you’d run it in a  
command that detaches.
