There doesn't seem to be any way to set 'click to hold' any more in the trackpad preferences. This means that you can't drag and hold windows any more. whenever the 'tap' is released, then so is the drag hold! This is a problem if you are moving along a big distance, e.g. across the whole screen. (Try dragging a Safari window from the right hand side to the left of a 27".) It's even more of a problem in games, as it is impossible to keep hold of an object! Is there any way around this?
