Please see https://github.com/racket/racket/issues/1408. This caused a lot of trouble for my students this year, but we lived with it---I am hoping it will eventually be fixed.

Also...

Looking at the code, it seems like it is calling methods like set-max-width (and others) in an illegal way. In particular, it is calling them from threads that are not the eventspace main thread of the frame containing the editor (receiver object for the set-max-width method). The code seems to be going to some trouble to cope with this, so it may be relying on invariants I don't know about, tho. @rmculpepper may know more, as he is the author/maintainer of this code.

I'll try to look at this issue again this weekend.

Thanks, if you have trouble reproducing the error, try disabling macro hiding.

Btw, the macro project is due Sunday, so this is no longer urgent for my class, but it does need to be fixed eventually.

Best, -CR

P.S. I think this is a thread race condition. Try hitting "Next Term" quickly (before Rendering Term is done), with macro hiding disabled.
