As the title says - when calling emu:runFrame() in the scripting interface, the emulator freezes. Not sure what I'm doing wrong here.

Are you running it in a loop? If so, don't do that. You're supposed to use callbacks.

I am not - I'm calling it once. Just "emu:runFrame()" in the entry box.

Loading a ROM of Ruby, pausing with CTRL+P, then running emu:runFrame() like this causes the emulator to freeze up, and I have to forcibly kill it.

Tried on build 686eee4, it works literally once per pause. If I pause, the first time I run emu:runFrame(), it properly advances one frame as if I'd press CTRL+N. Running it a second time without resuming and re-pausing emulation causes a freeze. This is not the behavior in v0.10.0 - it freezes each time.

More details: when the freeze occurs, emu:runFrame() remains in the command entry textbox rather than moving to the list of previous commands. Also, running emu:runFrame() while the game isn't paused does not trigger a freeze.
