I just saved an open Library problem to a local Drive in my webwork course.

I got an error statement without making any changes except for the filename.

The new name I gave to this file was:

Payer/M105_HW_10/Overlayed_fprimes.pg

But in the error statement the reply stated that I named the file:

But I did not! What would cause this error?

Thanks, tim
