I've installed MM7 from GOG installer, and hotkeys won't behave.
I like to use the keyboard instead of the arrows, I can set hotkey the way I want, but then, coming back to the game, the "z" key opens the information panel instead of going forward.
FYI this is an AZERTY keyboard, so instead of WASD we use QZSD.

I tried to install the unofficial patch to have mouse look, but it seems I'm not able to make it work.

Windows 7 64 bits family edition, if that helps.

Edit : Oups ! I can't find MM7.ini anywhere. Does it even exist ?

You must start a game for it creates the ini file,
but if you tested mouselook, that should be good.
So I don't know what happened. Maybe you must install the game with admin rights.

I think it was Windows 7 UAC that forbid the game from creating the ini files. Once deactivated UAC, starting the game created two ini files. I found mouse look in one of them and now it works. :-)

I can't modify to the title to put [solved] in it, and I can't select my own post to mark it as a solution ?

Well, the issue is no longer.
