Date: Wed, 25 Feb 2004 06:41:17 -0500 From: "Ryan C. Gordon" Subject: Re: MacOS X bugs... This isn't an ideal patch (trying to open a joystick that has previously been unplugged will report success, but it'll just never give any input, etc), but it handles the worst case of deadlock in the event subsystem.
