I recently upgraded my Palm device to a Treo 755p and installed FT on the external memory card. After playing a few days I realized the game had installed inself on the Treo's main memory. I deleted that but left the game on the external memory but ended up losing the entire game history up to that point. I started again using the external files and again it has moved to the internal memory. Is this what it's supposed to do? I do not recall this happening on my Clie?
