Deep breath now - and most humble apologies... after WRACKING my brain over these issues and proving there were no "config" differences at play due to several fresh re-installations of Opus - I've now figured out the crux of the problem.
All this dysfunction appears to be related specifically to Libraries... I really should have realized this much earlier after the initial few issues I found with various control codes not resolving properly when libraries are involved. But as you can see from all the spewed verbosity in this thread - I've been on a mad scramble to try and get things that have always worked on my old system - working on the new, and I've started using libraries alot on my new system. Sigh...
You can ignore every variation of things not working as expected in this thread... I've reproduced all of the issues on the old XP system when I throw libraries into the mix there as well...
Ah nuts... I filed mine also (just now, before reading your post here - and hours later in-between work). Mine is typically verbose... mainly from listing a couple of variations that change the actual "result". Maybe it's not needed... hopefully a single relatively simple change corrects the various differing results you get with different combinations of how you might use 'Copy ARCHIVE'... The 'Copy ADDTOARCHIVE HERE' command from the default Operations->Archive Files toolbar button works fine. Maybe there was something done in that particular copy command option that could be re-used in 'Copy ARCHIVE'.
