Here are 2 (possible) problems in Think C v3.0 (I won't call them bugs since they may or may not be): 1) The Debugger. Every time I interrupt my program to get to the Debugger, it changes the windowKind field of my program's windows to userKind. This is a wrong assumption on the Debugger's part, IM-I page 276 states: "UserKind represents a window created directly by application calls to the Window Manager; for such windows the application can in fact set the window class to any value greater than 8 if desired" I use the windowKind field to differentiate between windows owned by different modules in my application. At least they could have documented this *feature* in the manual! (I use the window's refCon for other things, so don't tell me to use it instead) 2) PopUpMenuSelect I don't know whether this is a bug in the MacTraps library or in the the Mac II ROMs Menu Manager. I am writing a MDEF for a popup menu. When the MDEF gets called with a message of hPopUpMsg (3), the coordinates of hitPt (top left of PopUpItem) are passed to the MDEF the wrong way around. That is, the right-hand word of the Point contains the vertical coordinate, and the left-hand word contains the horizontal coordinate. Could someone please verify these happenings? -- Frank Ng ACSnet: frankng@basser.oz Department of Computer Science ARPA: frankng%basser.oz@uunet.uu.net University of Sydney NSW 2006 UUCP: uunet!munnari!basser.oz!frankng AUSTRALIA

Yep, that's a bug. I've tripped over it too. The reason it changes has to do with MultiFinder, but it should report the correct value in the data window. The work-around is to go into TMON and look at windowKind there. Another field that gets changed is updateRgn. If you're updateRgn is not empty, when you break into the Debugger, it saves away the updateRgn and clears it. When you start up it restores the updateRgn. Again this is to protect you from a "feature" of MultiFinder. -- Jerry Whitnell jwhitnell@cup.portal.com ..!sun!cup.portal.com!jwhitnell
