My app has 10 activity modules. Only 8 show in the tabs and the pull-down list in the environment, so I can't access the last two. They are loaded though, as the app compiles and runs fine, and if I try to "Add existing Module" to get them to load and show, the error message says they are already loaded. I rebuilt my project, loading the activity modules in a different order. Again, they appear to be loaded, but after the first save and reload I can't access any beyond the first 8, even though the compiled program has the modules there. To be clear, I am aware of the pull-down list when I shrink my environment, and they don't show in that list. Likewise, when I make the environment full-screen, they don't show in the tabs. And varying the order the activity modules are loaded consistently fails to show tabs for any activities beyond the first 8 loaded.
