Question: Preview stuck on markup tool
I used Preview v 9.0 Mac OS 10.12.6 to markup an image.
Now when I open any image e.g. a screen shot in Preview, it is stuck on the last markup tool I used (the Add Rectangle Tool).
What I need to do is to tell Preview not to use ANY Markup Tool on an image but I cannot seem to do it.
Any idea how to accomplish this?
