Ok, this will probably sound weird, OR there will be some all too simple fix and I'll feel stupid, but if I get my problem fixed, I'll be happy.

First off, AutoCAD is not deleting stuff. I can select it and hit the delete button on my keyboard, and NOTHING. I can select clear from the EDIT dropdown menu, and NOTHING. It is annoying cause I KNOW it was working yesterday... I swear it was. So question is, what did I do between yesterday and today and how can I fix it?

Also, a bit quirky is when I select something and want to move or copy it, it acts like I have not selected anything and asks me to select objects.

Ideas?
