This may sound like a totally useless question, and I'm probably overlooking something obvious in the process, but why is InsertMenu being called whenever there's a mouse down in the menubar? This is being done by the system, not by the application. If there's an item in the menubar, shouldn't it have been placed in the menu list by the application already? It just seems kinda pointless to me... ______________________________________________________________________________ Dean Yu | E-mail: mystone@caen.engin.umich.edu University of Michigan | Real-mail: Dean Yu Computer Aided Engineering Network | 2413 Kelsey House ===================================| 600 E Madison "These are MY opinions."

For instance, one way that applications can set up a 'Windows' menu is to scan the window list when the user clicks on that menu, and create the appropriate menu items then. Another thing that could be happening is that the application is inserting hierarchical menus only when it needs them (ie, when you click on the menu). I tried reproducing your situation, but was unable to. I set up TMON to break when _InsertMenu was called. I then ran 3 applications (MPW, AppleLink, and SmartCom). None of these applications broke when I clicked on the menu. Finally, how do you know that it is the system that is calling _InsertMenu? Did you write the application, so that you know what is going on? If so, then the source of the call may be an INIT or something. After setting up TMON, I also called up OnCue. Sure enough, my Mac broke into TMON 3 times: once for the main menu, and twice for the 2 hierarchicals I had in it. ------------------------------------------------------------------------------ Keith Rollin --- Apple Computer, Inc. --- Developer Technical Support INTERNET: keith@apple.com UUCP: {decwrl, hoptoad, nsc, sun, amdahl}!apple!keith "Argue for your Apple, and sure enough, it's yours" - Keith Rollin, Contusions

I had placed a call to SysBeep in my patch to make sure my routine was getting called. (This is the first time I've used Get/Set TrapAddress, so I wanted to make sure I was doing it right.) SO my routine was getting called, and it beeped every time I clicked in the menubar. Let me ammend that statement about the ATB's. At first, I had set an ATB for only application calls to the trap. MacsBug didn't break in. I reset it to catch all calls to the trap, and it broke. That's why I think the system is calling InsertMenu. Although I admit it might be an INIT. ______________________________________________________________________________ Dean Yu | E-mail: mystone@caen.engin.umich.edu University of Michigan | Real-mail: Dean Yu Computer Aided Engineering Network | 2413 Kelsey House ===================================| 600 E Madison "These are MY opinions."

When I posted the original article last night, I had thought for a bit before I posted it whether it was really the system calling InsertMenu, or did I actually have an init that did it. I couldn't think of one last night. After reading Keith's article, I thought about it again, and I looked closer. Guess what? I had the Menu Extender init installed (I wondered how that got in my System Folder?) and that was doing it. My apologies to the net for wasting bandwidth. (I DID say in my original posting that I was probably overlooking something obvious... :) ) ______________________________________________________________________________ Dean Yu | E-mail: mystone@caen.engin.umich.edu University of Michigan | Real-mail: Dean Yu Computer Aided Engineering Network | 2413 Kelsey House ===================================| 600 E Madison "These are MY opinions."
