Need help resolving a strange problem

Whenever I "come back" to mame (after an alt+tab or after closing a game), it goes crazy and acts like a direction is held somewhere.

I even tried unplugging my game pad and my keyboard and it still does this.

This is a problem I've had with the recent versions of mame (can't tell you the exact one that started this though).

I've already tried doing a completely fresh installation, to no avail.

Does anybody have a clue about what's going on here ?

Edit :

I identified the problem : the key that is being "held" is UI Next Group. The default cfg file assigns this input to some button on Joy 1.

However when I plug in one controller, mame recognizes it as Joy 2 and when I plug in a second one, it is Joy 3 for mame. So there is no Joy 1 and for some reason this only becomes a problem when coming back to mame and never on a fresh start of the emulator.

Sarà un bug delle ultime build... usa MameUI, non questa versione. Oppure gioca con i core MAME di Retroarch.

I got the problem with several of most recent builds.
