Only (maybe) the fact that it's myself that is encountering this problem. There is no other user.

I'm not going to file a bug, because I know now that it isn't a bug. Like I said in my previous post, the behaviour for a similarly configured user in my test instance was different to prod and as expected; i.e SHOW TABLES produced a non-empty set; i.e. the expected behaviour.

Again - there is no "she". There is only "me". I appreciate your efforts to be inclusive & non-gender specific 'tho. There is no "command anomaly". The privs all show correctly as a result of SHOW GRANTS for the user(s) involved.

I have checked the privilege tables on both test and prod instances and there are no differences.

I have also tested prod with a user of the form "<user>@localhost" and this user did NOT encounter the problem. The user that encounters the problem on prod is of the form "<user>@<external IP>". A user of this form does not encounter the problem on test.

What log(s) would you suggest I turn on?
