Hi again. My apologies for being a bother. Michael, thank you for your suggestions and help, but the haven't worked. I've checked the snaps and they are already as you've suggested having them. Nevertheless, I turned them on and off and readjusted them before changing back to your suggested settings, sort of like whacking a machine a few times in hopes that a few kicks and shoves would somehow fix the problem. Sadly, it didn't. I'm attaching two screen shots showing the same attempt at drawing a rectangle with the snaps specified.

Thank you again for any help.

Bob
