Oh, I beg to differ; I think it can definitely be classified as a bug and it should absolutedly be reported to R&D. This is an undocumented change in a type of behavior that goes back to at least LabVIEW 3 or so and has worked by the same mechanism since LabVIEW 5.1. Given that the APP_ABOUT menu item can still be used to call a custom About.vi, and that it still works properly with the Default menu, I'm pretty certain that this was not changed intentionally. Besides of which, I know quite a few LabVIEW programmers that won't be pleased having to create a custom menu event handler just to avoid "About LabVIEW..." appearing in their application menus! Please report this to R&D and post the CAR ID#. Thanks.
