Trouble trimming wall

[Anonymous]

I am stumped as to why I can't trim a wall. Since I needed to show several pictures I have attached a file (word) that includes the pictures and an explanation of the issue. I have some thoughts on what is happening but I am hoping that someone can explain the current behavior. It should be noted that the windows in the wall were created by placing the first window in the wall at the 6 o'clock position. Then I dragged multiple windows (counter-clockwise) around the circular wall. I am wondering if the issue of losing the windows when trimming with the scissors is due to each other window needing a reference to the first window in the wall. I am also thinking that the issue of the wall just moving when trimming by moving the end point is the result of window references to the first window. I have several other ways to attack this such as using the SEO command. Personally I believe that the methods I used initially should have worked. All responses are appreciated.
