Installed TR too (333 build) and it works just as good as PDAWIN, although you have to wait longer before retapping the volume (like tap...sigh...tap instead of tap!tap!tap! which is irritating enough if you own a receiver with a very "fine" volume control).
Wouldn't be surprised if the problem lurks from the dark secret place called "trailing edge".

What I do like in TR is the use of the hard buttons, however they don't match the 4 bottom pushbuttons on the Axim X3.
Anyone found out how to get that right?
