I have confirmed this one, just running existing control on MacOS X
PPC that runs fine in RB 2006r3 crashes on Event Instance in r4

Note the REALeventInstance declaration which is defined as:
void myControl_RectControlRemoveFromEventListHandler(REALobject
instance)
{
}
REALeventInstance WordGuiseContainer_RectControlEventInstances[] = {
{"EnableMenuItems", (REALproc)

Most of the RectControl events are simply removed, but
my_CloseHandler and my_OpenHandler are used to implement myControl.
In release 4 my_OpenHandler is never called (nor is
myControl_RectControlRemoveFromEventListHandler:

Sufficient to say: A win.exe fails too, it never reaches the
REALeventInstance.
Guess I have to wait for another alpha release.....
