Yesterday, I watched ianscott888 tutorial on drawing vertices. Great video. And for several hours afterwards, I was gleefully drawing verts on new projects and old. It worked fantastic. Then, it stopped working.
So, I went to every extreme to get the functionality back. Even reloaded Blender to make sure I had a good version.
Hold down CTRL+RMB. That's how it's supposed to work. But, now all I get is faint gray area bordered by white dots. Can you please help me figure out if this is a Blender problem or something I've done wrong? Will provide screenshot if allowed.
