Locked object dragged along with connector midpoint? Bug or PEBCAK?

Note that the large white "frame" (really just a rectangle) at the back is _locked_.

Select the little white box that the connector arrow is going into, then drag it around to move it. The large white frame moves, too, even though it's supposed to be locked. (you can select other stuff, too, as long as you don't select the box the connector is coming from.)

The root problem seems to be that the midpoint of the connector is somehow tied to the big white frame. If you move the midpoint, the frame moves. If you select and delete the connector, the frame disappears. But if you select them both, you can't ungroup them, so they're not grouped.

Is this a bug, a corrupt file, or did I somehow turn on a feature that I don't know how to turn off?

That large locked rectangle has become a line label for the line running up to the smaller box.

Any shape can be dragged directly onto a line to convert it to a line label, which is what I think has happened here accidentally.

So, regardless of its locked state, it moves around as the line moves around.

Think I'll muck around with locking line labels, etc. and at least file a bug about that.

Thanks for pointing this out, and I hope the above information helps.

Ok, that explains it. I did this again (intentionally), and I can see how I might have done it inadvertently.

Once I've dragged a shape onto a line, how do I remove it and make it a standalone object again?

Thanks!

You can just drag it off of the line far enough and it will become a "regular" shape again -- If you know you don't want to ever have a shape to become a line label there are controls for this in the Connections Inspector.
