Menu disappears

Hi all, I created a menu application. If I go through my different apps it shows up fine. But if I click on a link to one form the menu is not shown. Also if I use the back button from this form the menu doesn’t show up on the previous pages where the menu showed up before correctly.
I’m using the same templates on all apps.
Could that be any config error in this form?

Solved - I used “open in parent” in the link properties. Should be “open in the same window”.
