@ all:
Thanks for your replys and suggestions.
I think I´ll work a little to tweak it and add some features.
Maybe an inkey-dialog where you can give the materials names.
@ Grayson Peddie:
I´ve sometimes that problem with sliders, and I´ve no clue why.

The flags for the panel are "d3d, refresh, transparent;"
Do you have any idea what´s wrong with the sliders?
Anyway, thanks for the response

For your suggestion,
maybe I´ll implement the cursor keys, because for
me there´s no reason for them.

Maybe I´ll make buttons for up / down. Two little arrows or something like that.
@ tuschcarsten:
Mach mal! Was macht Easy-Cam 2 ?

Das war nämlich auch ein nettes Projekt.

Any other suggestions / bugs?
