See above: You have already a V40 in ROM. You cannot replace a V40 in ROM with a V40 from disk, *UNLESS* you also specify "DOWNGRADE". You can replace V40 from ROM with V42 from disk if you would have it.
It's not a downgrade. It's intuition.library version 40.86b7 from
here, that was discussed "to death" way back in
this thread. Version in ROM is 40.85. But I think I get it, now. This goes back to something mentioned in one of the previous threads on this subject - that unless you specify the file directly, AUTO only reads the major version number (40) and not the full "40.86". This is just an example, though - it's doing the same thing with all the libraries (
like in Kolla's case, it was trackdisk.device). Now I think I understand.
Ah well, so wildcards don't work, and AUTO doesn't work (with my particular requirements, anyway)... guess I'll keep doing it the "old fashion" way. Thanks!

If you want to override this, add "DOWNGRADE". But then don't come back to me and tell me that your system became unstable. It's then your problem.
Hey now, no need to get snippy. From a layman's perspective I had assumed what I was trying to do was pretty simple: automatically load an entire directory full of replacement libraries, devs, and handlers, instead of having to spell out each one in the Startup-Sequence. Didn't realize it would be so difficult, lol.

Thanks for your help, cheers!
