I think the forced CollectGarbage(); makes a big difference. I had the
same problem and calling this worked wonders. I remember reading that if a
page uses a newwin=window.open that you've created an explicit reference to
the new window and the 10-12 second lag (with layer intensive pages) is
probably IE waiting on an internal reference check or possibly the random
call it makes to it's own CollectGarbage();
Nice find Darryl. Probably sheads some light on the overall GC problem.
Thanks,
Ray
