The map loses focus when you return from project management

[harrywipperfuerth]

If the user opens project management and then switches back to the map, the map loses focus.

Currently the user has to "click" on the map again to interact with it.

This should be changed so that when the user switches back to the map, the map is always in focus and the user can continue working without an additional click on the map (this also applies to all other areas that still need to be implemented (e.g. TASKORG, Preferences etc.).
