I'm drawing on top of the HyperCard window with some xcmds and needto update my drawings when HyperCard gets an update event. What is really needed is the generation of a HyperCard message every time it gets an update event. This will allow me to re-draw my things as well. I've tried putting an EentAvail xcmd in the idle handler of the card and looking to see what it receives. It seems to get only some of the events, but it reliably gets the app4 event when I switch back to the stack from another app under multi-finder. 99%of the time this xcmd completely misses the update event, (I've seen it once). There are some new interfaces in HyperCard 2.0 that allow passing events to windows managed by xcmd's but I can't see how to intercept the normal events. (I only have early Snow documentation, so perhaps there is something I haven't seen). Please mail me or post any helpful hints. Peter Marks.
