I am not able to run the editor from the calibre beta when running from source. I am using the portable version with a bat file wrapper to set the appropriate paths and environment variables. When I try to open the editor, it will flash and disappear. If I run the portable version without source, it works with no issue.

While experimenting, I tried various ways of running the editor. They worked except for running from source with "calibre-debug.exe --edit-book". The below is from the Windows command line. I have added the SET and path display to show where everything is running. I don't think I have missed anything.

Using "calibre-debug.exe -g" starts calibre with no issues, but the editor will not work.
