I have a problem which I can't solve. The application uses a BorderLayout, north is the JToolBar, south status bar and in the center, there is the main frame. When I open a window, it appears in the center. When I want to resize the window manually via the resize-cursor, the toolbar vanishes and after closing the window, the toolbar appears again.
Here is the Main Frame without the toolbar
Is it maybe happening because of the ActionListener/event or the border layout itself?
I cant really show the code, because its a multi module code with long lines.
Has anybody experienced such a weird behaviour? Where should I start to solve this?
