Bellowing is the steps to reproduce the problem:

1. generate seesaw project template

2. Add seesaw to Leiningen `project.clj`

3. Now load project source files with CIDER and evaluate the `-main` function in `src/hello_seesaw/core.clj` file:

4. It displays seesaw window, I closed it. Then CIDER REPL buffer displays red message reports that CIDER is closed.

CIDER version: `0.26.1`  
Emacs version: `28.0.50`

You set the :frame to :on-close-exit, which means that (System/exit 0) will be invoked when the window closes. This is a typical setup if you have a pure gui app where closing the window means exiting the program. You don’t want this during repl development, so use a different option, :hide, :dispose, :nothing. You probably want :dispose
