Thanks for your reply, Michael.

I think my issue with #1 was using an old computer. Upon testing the command on a newer machine, the graphical artifact did not appear.

As for #3, it's really only a matter of convenience. If I were to have a frequent need to affect snapping states in such a manner, I'd just shove those statements into a couple functions and be done with it.

Again, thank you for being so prompt in communicating with your customers. It's a rare thing these days to have such a direct line of contact with a software developer.
