Thank you for your help.

3.reason:

The crash during close window is caused on some setups sometime by some bug in Apple's CoreVideo framework. I've spent days not being able to fix it, just confirming it is Apple's fault and no workaround in the book for these kind of bugs works. It happens occassionally on my machine as well, both on 10.7 in the past and on 10.9 now. If it works for you then just by chance, just as if it fails for you it is just by chance. Some race conditions somewhere. Maybe the execution timing of some code has changed in the last beta a bit and now makes it less likely to crash.

There's no winning on Apple's OSX. I should probably kill off that function on OSX, it has only limited value anyway due to other Apple bugs in CoreVideo which haven't been fixed in at least 5 years.
