Gimper, I have to object. If I use move-tool, I move whole the layer, even if I alpha-selected the button before. But at last I could find the way: after alpha-selection take select rect. or el. regions and draw with the mouse. This simple thing took a lot of time. It is interesting that the selection changes when I draw, it will be so long as if I selected all the buttons, through 4 layers. I wonder, why. But good luck, only one button moves. I think, this is not so much logic in this, but now I know how to do.
