Okay, so, I apparently can't do anything right. Now I missed the quotes surrounding disk name in the user-startup file.
That means JAmiga will work when freshly installed, but not when rebooted (if you have spaces in your drive name).
Either wait for new os4depot archive and install again (sigh!), or simply edit your s:user-startup.
If you have spaces in the JAmiga path, please add double quotes on your path, from something like:
;BEGIN JAmiga
assign JAmiga: Amiga OS 4:System/JAmiga
;END JAmiga
to:
;BEGIN JAmiga
assign JAmiga: "Amiga OS 4:System/JAmiga"
;END JAmiga
New archive in os4depot upload queue...
