ePSXe Android: Random, spontaneous force closes?

I'm having some problems with my Android phone regarding ePSXe: Sometimes while playing a game, it just randomly quits to the homescreen with no "Unfortunately, ePSXe has stopped working." message. Most of the time, I can jump right back in and resume immediately, but it's still incredibly annoying. It rarely happens with native Android apps, but it only merely hits the pause button on those, and it never happens on any of my other emulators. Any help in this matter would be much appreciated.
