I have found that when you replace a member in a frame, the end treatments on the members that mate to the new member have an error or wraning.
When I select the end treatment to edit and fix the error, the buttons are not selectable. It would be really noice if the members would fix them selves. If that is not possible at lest let me select a new face to trim to instead of having the delete the treatment and recreat.
If you can't do that then why show me the error. Why not just delete the end treatment for me.
