Fixed. The main problem is that `on-subwindow-event' implementations are more restricted than they used to be. Due to the way that events are dispatched, if an `on-subwindow-event' method takes too long or if it requires threads other than the eventspace thread to run, then the event being processed never makes it to the native control (even if `on-subwindow-evet' returns #f). I think we may be able to improve the "too long" restriction to some degree eventually, but I see no solution to the synchronization restriction.
I made "orbit-mouse.rkt" work by changing the implementation of a queue within FrTime, which makes the `on-subwindow-event' hooks used by Fred sufficiently cooperative, and now mouse events can reach controls like sliders.
