Can someone tell me what I am doing wrong here?  I've got an application 
where I install a few AppleEvent handlers, but when those handlers get 
called, the AppleEvent parameter is always NIL.

I install the handlers like this:

err = AEInstallEventHandler(kCoreEventClass, kAEOpenApplication, 
NewAEEventHandlerUPP(AEOpenAppHandler), 0, false);

The handlers are prototyped like this:

OSErr AEOpenAppHandler(AppleEvent *theAppleEvent, AppleEvent *reply, 
long refCon);

And this is one of the handlers:

OSErr AEOpenAppHandler(AppleEvent *theAppleEvent, AppleEvent *reply, 
long refCon) {
    AEDesc        nameParam;
    OSErr        err;
    
    err = AEGetParamDesc(theAppleEvent, keyDirectObject, typeBoolean, 
&nameParam);
    return noErr;
}

When put a breakpoint in the AEOpenAppHandler handler, theAppleEvent is 
0 (NIL).  What would make this happen?  Something wrong with the way I 
installed the handler?  Something not set correctly in the SIZE resource?

I'm confused here.  I've done everything the same way I would do it for 
scripting additions; but it's not working like I expect.

Any help appreciated.
