Thanks for the input (Dadgag I believe you confused another poster with me). What is not working now compared to before, is the ability to add or remove to a set (using "a" or "r") without a command active. Quite often I would make a selection then add or remove to the set and then press the "delete" key. I am no longer able to do this. I can only make the "a" and "r" work when I have a command active like "move", "rotate" etc.
I suppose I could use the erase button to accomplish what I am trying to do, but it sure would be nice to be able to skip that step. In fact, prior to this change I often thought about taking the "erase" button off my sidebar as I never used it.
