Just a few questions for those few (in this early 7.0 stage) in the know: Does the Help manager look at MenuDisable to determine which baloon/resource to display? If so, does this "looking" occur before or after MenuHook is called? Obviously, I am trying to "coerce" the Help Manager to display a balloon not associated with the actual menuitem the cursor is over. (I do have a valid reason for doing this; I'm not making any virus to really confuse new 7.0 users!!!) If, of course, I'm barking up the wrong tree please let me know (and if you know I'm barking up the wrong tree, you probably know which tree I should be barking up and may want to tell me so...) Thanks... 'The Tweaker'

It passes the menu flags long word to the Help Mgr and that flags long contains the enabled/disabled info for each item in the menu. The other thing that involves the decision of what 'hmnu' resource to use is whether an application has called HMSetMenuResID() or not. (the HMSetMenuResID() call allows the remapping of menu id to resource id) An MDEF can also call HMShowBalloon() with the method parameter equal to kHMSaveBitsNoWindow. In this way there is no association with an 'hmnu' resource for a menu item balloon. Randy Carr System Software Apple Computer, Inc. P.S. I wrote the Help Mgr.
