I am not sure I remember it correctly, but does Cyphre mean following? :
when you hid face, containing sub-faces, all timer in subsequent faces are
stopped/removed from queue? Cyphre?

>From the times of first alpha of View I suggested ability to hide mouse
pointer. That will be needed for kiosk mode (full screen). I suggested to
replace mouse pointer with face, containing sub-face, placed somewhere in
system structure. Imagine transparent face containing some 100x100 hand
pointer, where subface of some 20X20 would be sensitive, e.g. finger
pointing at target ...It can be of course done even today, but how to hide
that mouse cursor? :-)
bt: what about event transparent faces? Or even alpha transparent faces?
E.g. some rule which would allow events to be sent to underlying face, e.g.
famous Tao Intent capability, where you have ring, and boing ball in
background. You can catch/move boing ball in middle of ring, as it is
transparent ....

I thought so ;-) But we want shadow of the beast to be ported to View :-)

heh, I just hope your answer doesn't upset Cyphre, as I can bet he talked
about in in Express conference, as well as sent it to feedback, from which I
can bet, he haven't received any feedback anyway ;-)

I just wonder - what techniques does flash use allowing it fast and nice
effects, movements, etc.?

so give us some not so huge general ability to create own effects :-) You
know, we want Rebol to become distributed Scala in multimedia quality. If
you would allow us to live inside of browser, that would be end of
JavaScript :-) Of course you would have to support link to browser document
object. Killer app imo ...

Not sure it is worth the effort then ... better concenrate on Rebol 3.0 and
fine granularity of IO :-)
OK now, who's gonna do compiler finally? :-)
