When I select a piece of audio or MIDI on the arrangement window, the all entire project is selected. When I double click on it every single audio/MIDI open it own window. Quite a nightmare.
The funny thing is? It does only happen with one project. I open up another project and it seem to be just fine.
Aren’t these events Groupped? If you can see the “V” symbol in the right-top corner, then they are Groupped. To ungroup them, use Ctrl+U (Cmd+U) Command, or Edit > Ungroup menu.
