wine users - Jul 2010 - 4Winds freezes

I'm trying to run 4Winds
(http://appdb.winehq.org/objectManager.php?sClass=version&iId=15882&iTestingId=54861)
on MacOS X. Game generally works but sometimes, when finishing the round main
window freezes (only the playground, menu and buttons still works properly). I
was trying to run wine in debug mode but found nothing.

I noticed a possible cause of the problem. When main window freezes and start
new game without restarting X11 in terminal appears:

Code:
wine client error:15: pipe: Too many open files

 But don't know what to do with that.
