[Drawkit] double free

[James Maxwell]

Hello All,

I'm getting a malloc error "double free" when trying to drag guides on  
my customized guide layer.
Putting a breakpoint at malloc_error_break shows that the problem is  
coming from DKToolController's -mouseDragged: method, specifically the  
[pool drain] at the bottom. Anybody have any wild guesses as to what  
might be causing this? I know it's pretty much impossible to know  
without seeing my code, but perhaps there are some obvious things I  
should check?

thanks,

J.
