Debugger can create a morphic error when saving new code

[jecisc]

It happens often to me that when I save new code, a red square of death appears. Then I get a new debugger about that.

I think there is a very old issue about that. If this is the one I'm thinking about, we are not able to reproduce it on Mac.

What OS do you use ?

I was using Windows, and it’s true that I do not get this error anymore since I have a mac

Maybe we could investigate this during the sprint on Windows.

This happens when you save the code while the code completion popup is open
