A PR to improve `struct->vector` for CS would be welcome. There
relevant code is here:
https://github.com/racket/racket/blob/master/racket/src/cs/rumble/struct.ss#L1221
As you'll see, the synthesized name is currently whatever comes out of
Chez Scheme's `inspect/object` interface. It could instea
We may change Racket CS so that it produces the same results, but in
general the results of `struct->vector` on values that are opaque is
not something that should be relied on.
The describe library is, I believe, unmaintained, and hasn't been
updated in many years.

I know only that we didn't get the report with earlier versions.
BTW, if one click on the dialog that has the error message, there should be
a "copy" option that will let you get some potentially valuable debugging
information. If it is easy to get a student who is having the problem to do

We have had one other report yes. It looks like something is going wrong

I have two students who just installed DrRacket on Windows 10 and get this
error when they try to open files:

string: #"\340lU\1"
Has anyone else encountered this?
