Ricky, re new ST6, when I use the CONNECT command to connect the middle of an element to something else, the element doesn't highlight when I pass over the middle. Further, when I press "M" to attach to the MIDDLE, nothing happens. Other keys work, like "E" or "C" but not "M". I tried a generic mouse without any improvement.
Ricky, forget this one. I decided to check my INTELLISKETCH relationships. And sure enough, the MIDPOINT was unchecked. How it became unchecked is a mystery. When I first download ST updates as I check/correct my preferences, I take a screen shot of each option/setting. The screen shot shows the MIDPOINT checked. I would not knowing uncheck it for any reason. But it's ok now.
