Strange XY3 behaviour

[rrr@xxxxxxxx (Yo Intl.)]

Did I, after all these years, stumble upon a XY3 bug? I wanted to
save a file to floppy and typed "sa b:con". XY first told me
there was a file of that name (there was not), and when I told it
to overwrite, it completely freaked out. I rebooted and tried again --
same thing. What is this? Does the "con" interfere with the "con" DOS
command? Or was this just a fluke?
