The USA version of the game is unfortunately flawed when compared to others, and this seems to be another one of the flaws. I tried the French version and the design trashing with both mouse buttons works there. The French version also supports music, which the USA version does not despite the option being offered at startup. Also, if you press the third mouse button (typically a scroll wheel click) in the USA version then you'll be kicked out of the game due to some debugging code that was left in.

Yeah, I noticed that MOUSE3 closing the game, although it only happens when "autolock=true" in the config, with that set to "false" it just locks and unlocks the mouse from the window. And I didn't know there is other version of the game, any idea where I can get it?

EDIT: Nvm, just found the French version and you are right, it's working good, along with music. It feels like a slightly different game. I noticed that mouse cursor also can move out of the 'frame' so you can click items that are very low on the screen. Also people multiply faster I think. Thanks for the info about that version.
