Most of your email is clear enough to em, and I agree with the what you

I would like to remove the display code from [NSWindow -update] to fix
this. [NSApplication -updateWindows] would also be changed to send
-update to all windows, not just the visible windows. Since this is a
somewhat tricky issue, I thought I'd bring it up for discussion first.
Comments are welcome. :)
The documentation is pretty clear that -updateWindows handles visible
windows.
Why do you say it needs so send update to *all* windows?
The -update documentation sats 'An NSWindow is automatically sent an
update
message on every pass through the event loop and before it’s displayed
onscreen.'
So I think that off-screen windows are supposes to be sent an update
before they
are made visible ... and if we change the code to do that, do invisible
windows
need to be handled in -updateWindows ?
