[issue38946] IDLE on macOS 10.15 Catalina does not open double-clicked files if app already launched

[Terry J. Reedy]

Terry J. Reedy <tjreedy at udel.edu> added the comment:

With Mohave, double click on a file name in Finder Documents opens the file in an editor and then opens the shell.  Double click on another file opens the file in another editor (but not a duplicate shell).  These are .py files I saved from IDLE.

Ramon originally posted this on Stackoverflow, where it is slightly off topic.  I suggested posting it here to at least have it documented and see what Ned says and for the off chance that there is something we can do.

I wonder how a downloaded file could be different from a saved file.  Are file permissions as revealed by 'ls -l' in the directory in Terminal the same?
