Comment 8 for bug 467179

This bug applies to me too, I think... I have a quad core desktop (Karmic) and ps tells me that openttd takes a little over 100% (indicating one whole core - that is, it would go up to 400% if a process was taking all cores). I've attached a ps aux from various states in the game. The reason I found this issue is that when I quit the game it doesn't close. The screen just hangs with the mouse pointer over the "Yes" button (screenshot attached).

I'm using the 1.0.0 beta1 version of OpenTTD, I'm not sure if this is the right place to log this bug (I'll log it at bugs.openttd.org as well).
