Dear friends! I found an unpleasant error: if you turn off the copper layers, select a silkscreen layer (lower or upper), then there is no selection of a group of components. I can select one component by holding CTRL to select multiple components, but the selection of a group (a rectangle with the mouse in any direction) does not work. This is very inconvenient. Now it is impossible to select only components without affecting the tracks. Probably, the selection of the group should take place on the active layer.
