This I already did and wrote an email to the list - this fixes example
17 but not the other examples.

This solves the problems for the grey page. After you run a program
the first plot will be shown (after a short while if there are
multiplots). This is for the carbon qt binary, but I expect this to
work also for the cocoa qt binary. The only thing left now (apart from
this color crazyness) is that the window is in the background when you
start it. Is it possible in Qt to bring the window into the
foreground, since this is something the user would await? I'll commit
these changes.

It must be something like that since the cocoa library of the same qt
version doesn't have these problems. That's really strange that Qt
somehow overloads the stdlib functions with buggy functions.

It's actually not much a problem, maybe the wiki helps you a bit:

Congratulations to you and your wife about the upcoming birth! I wish
you all the best and I'm sure it will be a great time for all of you.

Werner
