Morning I've been working on a box culvert drawing for a few days. Yesterday as I was finishing a revision I don't know if I inadvertently hit the wrong key or what but now in paper space I cannot get a viewport command to unlock. If I highlight a viewport, right click to get the option to unlock it does not display the option. In the layer display bar in upper left the layer display will not change to the layer I'm clicking on. It does not display the layer of an object. Finally at the same time I cannot no longer edit text in either paper space or model space. I can highlight it by left clicking on it but it will not offer the the option to edit the text. I'm Working with Civil 3d 2012 version. Seems somwhere I hit the wrong command and locked certain commands. Any ideas? Thanks in advance.
