Re: RNX1251 (Perm I/O error on display file) bugger headache

Thanks Barbara!  That's helpful.  We have not thought to vary off/on the
display device, since the user continues working on other applications
after getting this error.  In terms of recovering from the error, I've
passed on the suggestion to close and reopen the display file when the
error occurs.
