Please don't play with variables, the next update WILL have a (configurable) hotkey to open the menu and the auto-close feature, which seems to have confused lots of users (it wasn't "random" it was made to save from as many double clicks as possible), will be gone.
Of course, this won't change the limitation that is not possible to run the menu if the toolbar icon is not active, which means the first time you start GSX, you *must* open it from the Toolbar icon and never close it so, as long the icon stays active, it will respond to the Hotkey. Same as Navigraph charts, for example.
