Re: Crashes with NSOpenPanel and garbage collection

Apparently it has already been logged and should be fixed in the next 
release.
I'll just have to add code to my app to check for 10.5.2 and pop up a 
box telling the user to upgrade their machine.  Something like "10.5.2 
has a nasty bug, please upgrade, or if you don't want to, don't bug me 
error reports because there isn't anything I can do about it :P" 
should do the trick :)
