After some action openttd lose input. It no longer act on mouse/keyboard events, without any other effect in game (tracs still move, air planes still fly)
Did you try changing the Video driver from Allegro to SDL? That not only improved performance for me but also got rid of that problem. Change the settings in ~/.openttd/openttd.cfg
Man, its 10 time faster!!! Why its not default? I will check bug, and report if problem persist
played for several hours - no bug present in SDL
This bug appears to have been reported against 'rawhide' during the Fedora 11 development cycle. Changing version to '11'. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Closing. OpenTTD is now built without allegro (which actually was intended to make OpenTTD compatible with DOS). Thus this error has disappeared. It will however still be reported upstream.
