A number of times I have seen things change in my drawings. A wall may get longer or an item may take on a different class. Each time I assumed that I did something to cause the change.
Today I find that the sound preference came on all by itself. I did not check the box in preferences, yet without reason, I now have sound. When I open preferences, sure enough the check box for sound is checked, but I did not do it.
Is there a check box to turn off these gremlins?
