You know , right click anywhere on the adventure map and you are supposed to get a little box with relevant information, especially useful when you want to know whether to attack a hero or town or not.

This doesn´t seem to be working well on my setup. Only when I release the right mouse button do I get the info box for a fraction of a second. Anyone else getting this behavior? Any way to work around this, maybe a secondary way to bring up this information?

I´m on a core 2 duo laptop running Windows XP Professional.

That is still strange. The little box with information should appear if you press and hold the right mouse button.
Moving the mouse shouldn't have any effect.
