I too, have used JClock for quite a while, with both floopy and hard disk
systems, and have yet to experience a JClock related crash.  However, there
are good reasons for NOT using JClock:

1.  JClock just writes to the menu bar w/o checking for things which are
	there.  Most notably, Pyro! dosen't work very well with JClock since
	Pyro! will blank out the screen, but JClock will continue to write
	the time on the upper right hand corner (of an Plus/SE/512k).

2.  JClock dosen't check screen size, so it in the wrong place on a Mac II
	(I know this can be patched, but it then won't work on a
	Plus/SE/512k)  It also appears in the wrong place or outright dosen't
	work with some virtual large-screen INITs for the very same reason.

So what should you use for a clock?  I use Menu Clock 3.0 - it works with 
virtual large-screens, Pyro!.  I think it'll also work on a Mac II, but I
don't have one to test.  Junk JClock - use "correctly" written software!
