When I clicked the right button always "undo" on the top in right-click-menu, but today, when I clicked the right button snap to glyph and unlock image are on the top. How to let these two functions won't show up in right-click-menu again?
Oh okay, now I get it! Thank you.
Notice Monika called it the "contextual" menu. That's because the items appearing on it change with the context. The menu content will change depending on object selection, tool selection, last operation, etc.
It's really annoying me! I'll try post on bugs & feature requests ...
