I was looking at the "Tweaks" that were posted in "psycho_maniac" sig which are TP tweaks but most of them will still work on the TP2 , and wanted to do the same that you were asking, I am running 12/6 MM dont know if it will work on 12/19 MM but it should, it did on the 12/6 MM.
"Set HTC Album X button to close not minimize
Code:"
HKLM\Software\HTC\HTCAlbum\
Set "ok_minimize" to 0
Give "psycho" a thanks for his effort and time for listing the tweaks..
