All of a sudden I have lost a couple of features which to me are important.

Previously I could select objecks in a drawing by clicking on them. I could select an infinite number of objects an then rightclic getting a sub menue in which I could inwoke  various commands affecting all selected objects.

Now I have to choose a command from the command icons and then select an object to execute the command.

How can I select many a number of objects?

How can I get the submenue by rightcklic after selecting the objects?
