Little fix for deferred events

[Steven Swerling]

Hi Rob,

You need ought to yield the processor when processing deferred events.
(changed method below, w/ Processor yield statement).

WxMorphic is about done now. It's quite stable at this point, works
great. I'll get it up sometime this weekend.

regards,

Steve S.
