slider - mouseball (a.k.a. 'wheel')

This is a question for those who can test it. You need a mouse with a trackball on top instead of a simple wheel.

With the trackball you can scroll 2-way (handy for photoshop, level editors etc.). In B+, sliders are automaticly updated when you use the trackball. (you don't need to do anything special for that..)

However, the code below has a quirk as it seems, trying it explains what I mean..

(Still using b+ 1.34, hope that isn't the problem here :))

app=CreateWindow("..",0,0,460,460)

c1=CreateCanvas(104,4,80,80,app)
c2=CreateCanvas(104,204,80,80,app)

sl1v=CreateSlider(184,4,12,80,app,0):SetSliderRange sl1v,4,32
sl1h=CreateSlider(104,84,80,12,app,1):SetSliderRange sl1h,4,32

sl2v=CreateSlider(184,204,12,80,app,0):SetSliderRange sl2v,4,32
sl2h=CreateSlider(104,284,80,12,app,1):SetSliderRange sl2h,4,32

quit=False

Repeat
	WaitEvent()
	If EventID()=$803 quit=True
Until quit
FreeGadget app
End

additionally: if you place the 2nd set (canvas, sliders) at the right side from set 1, and not _beneath_ the first one, then there seems to be no prob. ..

Is it useful somehow to have a trackball top of a mouse? I hope your not developing with that in mind ;)

Once you had the experience to work with that, you never want to go back. This is my second mouse already (the first one is now in use on my B-system), and I recommended the same type to 2 others already. Anyway, as I say, it's way cool for design-stuff. Imagine a 2d map-editor where you use the normal mouse-movements for tiling and the ball for scrolling through your map.
