[Drawkit] New To list & DrawKit

[Graham Cox]

Hi Dick,

I don't really know what's happening. All I can suggest at this stage  
is that you set a breakpoint on [NSException raise:format:] and see if  
that gets triggered when the problem crops up, that at least might  
give us a stack trace which should indicate where the error is coming  
from. As you say it's a bit strange it happens on one machine and not  
another.

You could try deleting the preferences file and see if has an effect  
on the problem (~/Library/Preferences/net.apptree.gcdrawdemo.plist).  
This is the only other file that the DrawDemo reads/writes.

Do other Cocoa apps work OK? I have to wonder if it's something  
strange about your system frameworks though I'm reluctant to pin it on  
that when it could be anything. If you can get any sort of info out of  
the debugger at the relevant place post it and I'll see if I can make  
any sense of it.

cheers, Graham
