Bug? (Some of my) My Activity modules are not showing in the IDE

I have a project with 10 activities and two service modules

When I start up the project it will not show the last two activities in the IDE

If I do a search it will find them AND will now display them on the list of modules

I have zipped the project and can send

The IDE limits the number of open modules when a project is loaded (for performance reasons). You don't need to keep all modules open.

You can easily find any module you like with Ctrl + E or with many other navigation features.

Ctrl-E works perfectly - Thanks! Learned something new today
