Re: [Togl-chat] Mac OS X Tk internal headers

[William K. <wo...@ky...>]

Well, I don't know much about the source - I'm just building  
binaries.  Given that the same exact build (a universal binary of the  
whole thing) runs on PPC but crashes on Intel, I'd say it's not this  
bug.  Unless it has something to do with deeper OpenGL stuff also -  
my crash happenes in some OpenGL rendering.  The developers are  
looking into it.  Possibly buggy OpenGL driver for the graphics card  
(Intel GMA on the MacBook), maybe they can work around it.
