Think Reference is pretty nice.  Although, it only lets you paste the
_prototype_ - not the whole code example.  I wish they'd let you copy &
paste (sans formatting) like Inside Mac DA did.
 
But now on to more fun.  In my quest to make Popup menus in fonts other
than Chicago 12, I wrote a simple MenuProc and hooked up to it in the
manner prescribed by Think Ref.  When I didn't alter the MenuProc, I
could define multiple menus handling the same MENU resource, but now
it crashes on "_HClrRBit".  Here's the code, can anybody help?
 
menu=GetMenu(menuID);
InsertMenu(menu,-1);
DItem=NewHandle(6);		/* allocate 6 bytes */
intPtr=(short *)*DItem;	/* address those bytes */
*intPtr++=0x4EF9;				/* a JMP instruction */
*intPtr++=HiWord(ZingerProc);	/* where to jump */
*intPtr=LoWord(ZingerProc);
(*menu)->menuProc=DItem;	/* attach to MenuInfo */
 
DItem is a handle, menu is a MenuHandle, *intPtr is short, and ZingerProc
is a pascal void procedure.
 
PLEASE respond in E-mail, my news system doesn't allow threading...

p.s.  When I'm done, I'm going to post the source for my popup handler
as freeware.
