	Yes, it's unreasonable, since your temp file might get corrupted
or deleted out from under your program.  It's one of the things one must
do to work properly in a shared environment (even single-tasking if you
have a network filesystem).

	ExNext is the basic call used to examine a directory.  The full
explanation would get rather complex if you're not used to programming Amigas.

	If you submit a bug report, include the version numbers (use the
version menu entry from WB, or "version" from a shell).

	Simply prep it as you would a 2090.  Then reboot from a floppy WB,
and format the dh<whatever>: partition.  Then copy workbench to it (note
that it will be old filesystem, and slower than FFS).  Then reboot without
a floppy and it should boot off the HD.

	Your machine would have originally came with an install disk to
re-setup the disk.
