It doesn't matter if I have a drawing open or am working in a new/blank drawing, the commands will not start from those shortcuts. I also tried changing the shortcut key combo to something else and that did not work either. Other keyboard shortcuts using the shift and ctrl keys work but some do not. On all the computers we can cancel a command by using either escape or ctrl-c and on four of the computers the keyboard shortcuts work but not on the fifth one. I can type those commands at the command line and they also work. I can use the pull down menu (edit) and choose those commands from there and they work just fine. There are no third party add on routines interfering, I have scoured the CUI for problems and everything shows that the shortcuts are loaded and available. On one of those computers I cannot use the keyboard shortcuts for copybase and pasteblock (ctrl+shift+c or v). I have AutoCAD 2012 installed on 5 computers. I am at my wits end over this small thing.
