opening the desktop toolbox on hover was never going to work perfectly, and would be a bit of a problem for touchscreens (they make the mouse jump instead of moving smoothly) - so it no longer happens.
the toolbox just lights up on hover now, and opens on click. it still closes on the hover leave event, though.
this makes the code a lot less hackish and should produce the least frustrating behaviour possible.
it's also a bit more like the panel cashew behaviour.
