Double-clicking a file from finder doesn't open it in Wing when the editor is already active
Using macOS Catalina and Wing Pro, I have the following issue:
When Wing is NOT active and I double-click a .py file somewhere, Wing starts and opens that file.
Whenever Wing is already active, double-clicking a .py file does switch to the Wing window (changes focus to it), but it does not open the file. So any subsequent source files, I have to open from the file menu in Wing. It doesn't matter how many files I have open in Wing at that time (even with all files closed it doesn't work).
Completely removed Wing and all settings files, re-installed and tried again. No joy. This one is pretty recent and I have to say... not a fan.
