When closing a NerdTree buffer it will show a prompt about unsaved changes on the latest version of VimR, like issue #571, #516 that appear to have been fixed in older versions, but has broken again since then. I do not see the same problem for help buffers like reported in #530.
I'm currently using version: 0.36.0 (20220102.161018)
Steps to reproduce:
open VimR with an empty buffer
Open a NerdTree buffer with :NERDTree
Close the VimR window using the red quit button in the title bar
