Issue with Eric7 and Parallel Processing

[Detlev Offenbach]

Hi Jamie,

I hope you commented out the right line. That line appears twice in the 
file but only the one shown in the changeset must be commented 
out/deleted. That did the trick over here (at least on Linux). I'll have 
to re-test your script on Windows to see, if that makes a difference.

Furthermore, I would like you to post a screenshot of the 'Start 
Debugging' dialog.

Regards,
Detlev
