Can't exit settings menu when pinned to application
With Cinnamon in Linux Mint (and I think other Gnome 3 based environments) there is an option to "attach dialogues to parent windows". When this is enabled and I navigate to the Sound Juicer > Preferences
menu, the dialog that is presented has no close button in the window chrome. Further it completely obscures the sound juicer application window and dragging the dialogue around drags the main window beneath it, rendering the application completely unusable until I changed the Cinnamon setting to have normal, separate-window modals.
I would suggest adding a simple close button to the dialogue itself would alleviate this slightly odd corner case!
