TotalTerminal launches under wrong user

After updating to TotalTerminal 1.4.5, when I launch TotalTerminal directly, the terminal logs in under the wrong user account on my computer. Additionally, Terminal reads its preferences and profiles from that other account.

(I initially thought the update had dumped my preferences, until I realized that bash itself was operating under the other account.)

Quitting and re-launching Terminal (sans-Total) causes Terminal to use the correct account, with all the proper preferences—and my beloved .bash_profile!

I am using Mac OS X 10.9.0, with two user accounts.
