Video here (couldn't attach ).
I'm on SolidWorks 2014 SP5.0
I've noticed that when the extra panel in the feature tree manager is expanded the viewport doesn't update when changes are made (e.g. dragging the history bar in the feature tree) until the mouse is moved outside of the changed feature.
This can be annoying when I make a change (e.g. to a global variable) then sit there waiting a while, thinking that the computer is doing something. I then realise that it's actually waiting for the mouse to move before the viewport updates.
Anyone else experiencing this problem?
