Sorry to disagree with you guys, but your 'fix' is not the correct one. Even
though it might repair the use of the IDE, it is not the correct way to
fix the problem.

The findParentWindow() function is working correctly. It is *meant* to
return zero if the id does not have a parent window. I suspect that the
function is not being used correctly elsewhere in the win32lib, probably
the stuff that handles focus setting.

The version in 0.60.6 had a bug; namely it did what you have now 'fixed'
it to do. That was wrong.
