Dear "tlk"
I think that the drop down menu should stay unless another area of the screen is clicked, where currently it closes after an action is chosen.
E.g. for a previously selected product, If i want to select a radio and change the volume consecutively, I have to (1) select the B&ORemoteGui icon in the menu bar, (2) select a radio, (3) select the B&ORemoteGui icon in the menu bar (4) choose the volume .... and assuming the volume chosen is not good, (5) select the B&ORemoteGui icon in the menu bar and (6) reposition the volume.
