Add the pic mail to S2U2's exceptions (done in the registry) that way it won't lock if that app is running.
- For advanced users, you can edit the registry (\HKEY_CURRENT_USER\Software\A_C\S2U2) directly. Please remember to RESTART iLock2 after any registry settings changed, otherwise it won't work. The default values are added on the first run of iLock2:
ExceptionEXE0=iexplore.exe (disable S2U2's auto lock when ie is running)
ExceptionEXE1=VoiceCommander.exe (disable S2U2's auto lock when Voice Commander is running)
ExceptionEXE2=AlarmPopup.exe (disable S2U2's auto lock when Spb's Alarm is running)
ExceptionEXE3=SDDialer.exe (disable S2U2's auto lock when HTC's voice dialer is running)
ExceptionEXE4=
ExceptionEXE5=
ExceptionEXE6=
ExceptionEXE7=
ExceptionEXE8=
ExceptionEXE9=
ExceptionEXEisFG=1 (exception is checked against foreground application; 0 is checked against both foreground & background application)
