Hi Michael,

I followed your example steps:

> Draw 4 circles
> Select 3 circles and group them
> Select the last circle and click on the group name to add it to the group

and they work for me as they do for you. Thinking that it might have to do with nested groups, I named the first group Circles and then nested that within Shapes. I drew a 5th circle and added it to Circles and it behaved as you intend.

Must be user error because I went back to the original model (I'd worked on other models since I posted) and am unable to reproduce the behavior of modifying one of the Trusses and winding up with the Framing group selected.

For what it's worth, I had a series of trusses that needed to have longer tails, so I had deleted the top two members of all the trusses, then I redrew a pair of the correct length. I then copied the pair into the correct positions for all the trusses, and finally added each pair to the appropriate truss group. Each time I added the pair to the group, the Framing group was unhidden and selected. Once I'd fixed all the trusses, I used BatchRename on them and then saved the file. I have attached the model in case it contains any clues.
