I was a Mac tech for 11 years, fixing ~5000 iBooks, iMacs, PMG4s, etc. 

It showed me that everyone gets problems and computer headaches, they just scale with the competence and skill of the user, so beginners get simple problems, and pros get difficult to reproduce intermittent bugs. 

You must be quite the power user(s) to get this kind of problem - and I am so glad to see you guys solve it!
