Hi Emil, 
I don't think we have exactly the same configuration. :-)
My computer is a 3-years-old Asus eeePC 1005HA, with an single-core Intel Atom 
at 1.6Ghz, 1GB of RAM, a 200GB Hard drive at 5400 rpm (but with long response 
time), and a lot of scotch tape (and also a few optimisations to the IDE in 
order to make it faster to start).

I took a look at the profiling file, and I noticed that most of the drawing 
event is the panel moving :

panSelectN.Move(hCtrl.ScreenX - hRoot.ScreenX + 2, hCtrl.ScreenY - 
hRoot.ScreenY, hCtrl.W, 2)
    panSelectS.Move(panSelectN.X, panSelectN.Y + hCtrl.H - 2, panSelectN.W, 2)
    panSelectW.Move(panSelectN.X, panSelectN.Y + 2, 2, hCtrl.H - 4)
    panSelectE.Move(panSelectW.X + hCtrl.W - 2, panSelectW.Y, 2, panSelectW.H)

But I still don't understand what these panels are (I don't think that the 
frames are drawn with panels).

Making the "ghost frames" optional may be a good idea, but I find them very 
useful anyway, on controls that don't have frames, so that you can see where 
thay are exactly.
