Description Jesse Anders 2011-02-19 11:49:08 UTC 
In SDL_cocoawindow.m, at lines 728 and 732, the calls to 'setStyleMask' trigger an exception in OS X 10.5.8.

The exception is:

-[SDLWindow setStyleMask:]: unrecognized selector sent to instance

When building in Xcode, the lines in question generate the following warning:

warning: 'NSWindow' may not respond to '-setStyleMask:'
(Messages without a matching method signature will be assumed to return 'id' and accept '...' as arguments.)

The reference at:

http://developer.apple.com/library/mac/#documentation/Cocoa/Reference/ApplicationKit/Classes/NSWindow_Class/Reference/Reference.html%23//apple_ref/occ/instm/NSWindow/setStyleMask:

States that setStyleMask is available 'in Mac OS X v10.6 and later', which seems like it could be the cause of the problem.

Apologies if this is user error, and please let me know if you need any other info.

Ah thanks, this is actually really useful information drastically affecting a problem I've been wrestling with the past few days.
