Xperia Play problems with psx emulator

I’m having two problems with pcsx-rearmed

The touchpad doesn’t work, and whenever i touch it, the normal movement keys stop working for a few seconds. It’s really annoying.

Touching the bottom left corner of the screen kicks me back to the emulator selection screen. I suppose this is how you exit games, but i’d like to turn this off, since it happens way too often by accident.

I’m running Android 2.3.7

This question has been asked several times and, AFAIK, there’s not really anything we can do about it at the moment. You can wait for the new release and see if that helps at all, but that phone has been a real hassle to get working, due to the way it handles the gamepad buttons.
