Has anyone else experienced or is experiencing Chief freezing up while working?   When it freezes, I can see the cursor and move it around in the tools section at the top and in the docked windows on the right side of the screen but not in the workspace. It disappears in the workspace. Very strange.   The weird thing is, Chief will allow me to save the plan and the layout when it decides to freeze so only some of the functionality stops.   Thanks for any and all hel
