	Nothing is wrong.  Fonts are rather like libraries; they hang around
in memory until memory becomes short.  The reason it does this is so that it
doesn't have to load them off disk every time they're opened.  The fonts and
libraries will be purged from memory when the memory is needed.

	You can force the system to purge all loaded fonts and libraries
that are not currently in use by trying to allocate four gigabytes of RAM:

	AllocMem (4000000000L, NULL);

	This will always fail (unless you actually happen to *have* four
gigabytes of RAM hanging around (or if AmigaDOS/Kickstart ever goes
virtual)).  However, in the process of trying to satisfy this request, Exec
will make room in memory by flushing out all loaded fonts and libraries that
aren't in use.
