Hi Alex,
What we might have to do is extended the addView method so it handles
situations like your more seemlessly, i.e. do the realize etc,
however, one has to be careful about this as often you'll add views
well before you actually want them to realize. Perhaps the best thing
would to some kind of dirty mechanism that fires off a realize etc on
the next frame. Just to be clear, it's the lack of realize on new
windows you've added that is the problem?
Robert.
