In the 2.5.6 beta, the icons act as sticky keys always. I think it’s a bug, because in 2.3 it didn’t happen.
When I click an icon for example for extruding, then when I move the mouse it extrudes. If I do the same with a shortcut key I can go to the manipulator and drag as in the past.
Can this be disabled?
If it’s a bug: Having auto-sticky in icons is very uncomfortable. Please fix it.
