The file dialogs should not be changing. current-directory is a
parameter and the value of that parameter for DrRacket itself is not
changed. It is only the initial value of that parameter when running a
program inside DrRacket (and the program is in an unsaved file). In
any case, I'm unsure of the relationship between that parameter and
the file dialogs -- there may not be one; it may only be that on linux
they both get initialized in the same way.

If you see different behavior than that, tho, please do let us know.
