I have a toolbar for controlling music-app Aimp. If I press the button a second time (which will bring Aimp-Gui to front if already opened) I don't want DO to open the toolbar again (as toolbar-icons are slightly transparent, transparency gets lost with each overlapping toolbar ).
Actual command is following:
Toolbar NAME=_Aimp STATE=float,toplevel,transparent POS=1611,1349
