offset message, in bpatcher, to [thispatcher] of bpatcher = works
offset message, from root, to [thispatcher] of bpatcher = works
offeset message, coming from _another bpatcher = does not work,
even when the offset message is produced in root (fopr example
by triggering a messagebox).
does not work = weird drawing problem, old stuff isnt refreshed.
whats up? bpatcher refreshes fine when offeset from root, but not
when mouse is inside another bpatcher?
