In retrospect I agree, it was somewhat pointless. Like a good developer I was simply following instructions given in the error message written and placed there by Apple and also trying to improve my debugging skills. Error under OS X El Capitan 10.11.2 which is a little different that the previously reported error under OS X Yosemite 10.10.5. <Error>: Set a breakpoint at CGSLogError to catch errors as they are logged. <Error>: CGSGetSystemWindow: Invalid window > The time I saw your real issue was when I was trying to unravel some legacy > code that was forcing changes to the view hierarchy when in a drawRect: which > is really, really bad, and it was mixing up auto layout and manual layout—a > field editor and simulated combo box were involved. I actually was able to reproduce the initial first part of the issue with a standard Xcode 7.2 project template application. So it is time to give up and move on. It appears Apple will need to fix this. I updated bug report 23955382. --Richard Charles _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
