If you close the DSP Panel in a docked state and then close SDR Console, the DSP Panel will not remember the docked state after reopening SDR Console and then reopening the DSP Panel. It will always come back in a floating state.
Note, SDR Console will properly remember whether or not the DSP Panel itself was open or closed at the the time SDR Console is closed. It just doesn't remember the docked state of the DSP Panel if the DSP Panel was closed before closing SDR Console.
Also note, if the DSP Panel was docked and open at the time SDR Console is closed, it will properly remember the docked state in that scenario. If the DSP Panel was in a floating state and then the DSP Panel closed before closing SDR Console, this state scenario will be remembered after reopening SDR Console and reopening the DSP Panel.
If anyone wants to reproduce this and report the results to make sure I am not missing a dependency or have some unique problem with my particular install, have at it.
