Hey, no worries Adi! It's not like we wanted to release the beast tomorrow.

If it works indeed by sending an individual message for each view in R5, then
I must say, this is quite an overhead. I would assume that sending a single
message is much cleaner and faster. Resizing a single view (for example the
top window view) will result in all children with B_FOLLOW_* flags to be
moved and/or resized. On the app_server side, this is an "atomic" operation,
but when messages are sent for each view individually, I have a bad feeling
in my tommy, that this is a potential source of out-of-sync problems on the
client side. We could still emulate the single current message on the client
side and stick to the way I did it. What do you say?
Best regards,
