Re: PikoPixel hangs on startup

[Fred Kiefer]

First off, you are on the wrong branch. At the moment you investigate setting 
the minSize while your original problem was setting the frame of the window. 
That is the call in line 508 as it was reported in your original stack trace.

And for NSWindowTemplate it is of no surprise that your breakpoint isn't 
reached. You should move your breakpoint into -initWithCoder: somewhere near 
line 399. When saving a NIB file the method you are looking at gets used, when 
loading one it is never used.

Hope this helps,
Fred

On the road
