ctrl+shift+ (left/right arrows) (undo,redo) stopped working for me.
It used to be accurate but now I cant predict where it will take me.
It happened before, then got fixed, but now it looks like it is jumping to weird places.
cant make a sense out of it.
Same goes for the f4 in the form editor. it use to take me to declaration of the component in the code the but now it only puts me in the top of the class.
