Warcraft 3: Alt + Right Click disabled?

[agorex]

Hello! Warcraft 3 with wine works smoothly, but I have a problem. In DotA games, if I press Alt (to check enemy units' hp), then right clicking doesn't work (to move or attack).

How can I disable this shortcut (if there is one) or what should I do?

I'm playing in an openbox session.

Thanks.

Most games, pushing an additional key with alt should work (Windows key or space works for me).
