So today out of the blue, with apparent randomness VW 2013 his disappearing various drawing symbols/plugin objects. This is easier to show than to describe -screenshot attached - as I work along, various plugins or symbols begin to disappear, while still remaining in the drawing in place -as you can see from the selection handles showing in the scrn cap.
I have tried the incredibly unproductive close-everything-and-restart, to no avail.
Thoughts?
Advice?
Prayers?
