Line command activates when centerline icon is deselected. Crazy making!

Maybe it's the way I've learned to use the SolidWorks UI over the years, but sometime around SW2014 the centerline/construction-line icon started to behave differently.

My habit has always been to deselect the construction line icon when I have finished creating construction lines for a sketch I'm working on. In the old days, that was it. Back to neutral and out of sketch mode.

But now when I deselect the construction line icon, the line command activates. Which means I have to click one or two more times to finally get completely out of sketch mode.

This has been a nagging issue for me and I am embarrased to admit I can't figure out how to kill this behavior. It's driving me crazy.

Any suggestions for how to stop this behavior?

Thanks in advance
