No, _your_ checkin (removal of my code for B_VIEW_RESIZED) is the problem. 

The problem that my code solved, was that B_VIEW_RESIZED was not sent for all 
views that needed it. The way I solved this was to send a single message 
which contained the tokens from all effected views. The comment you removed 
explained where this was done in Layer.cpp and what the potential problems

This behaviour only happens after your checkin for Window.cpp. So I did 
notice, that's why I wrote the initial email. :-)

Oh, this will be greatly appreciated!! I think it has been quite obscure for 
everybody involved how to exactly (reliably) trigger a redraw.

Yes, thank you very much for your work! After your changes, I think 
app_server will be easier to improve further.

Best regards,
