In online bridge you might send a private message to the opponents saying that you had misclicked.
Heh, how can this be correct ?
Surely this the same as alerting a bid and explaining what you have in your hand as opposed to your partnership agreement - the opps now know more than your partner!

You may, if you wish. There is no Law prohibiting giving extra information to the opponents, and if you do, they are free to use it. However, you are definitely not required to do so. I personally do not.

...is there another law which says 'you can not announce to the table what you have in your hand' ?
Yes.

I was intrested in knowing the laws behind this decision and how they apply.
wbf 16A:
Extraneous Information from Partner
After a player makes available to his partner extraneous information that may suggest a call or play, as by means of a remark, a question, a reply to a question, or by unmistakable hesitation, unwonted speed, special emphasis, tone, gesture, movement, mannerism or the like, the partner may not choose from among logical alternative actions one that could demonstrably have been suggested over another by the extraneous information.
This means that if a player does receive unauthorized information, he is
(1) Not allowed to use it, but moreover,
(2) Must choose a call or play that CANNOT have been suggested by the unauthorized information, if any such alternative exists. You are not allowed to choose an advantageous call/play, and then say, "but that's what I would have done anyway."

My 2nd question is still unanswered - is banning undos (Law25) legal or just an online thing?
It is an online thing. Normally, in the case of ANY irregularity, the director MUST be summoned, and s/he then determines if any undo of bidding or play is warranted.
In non-tournament online play, there is no director, so undos are reasonable, due to computer/mouse glitches, although in my opinion they are far overused for brain glitches.
In tournament online play, it is appropriate to have the director make such decisions, but unfortunately there is no undo available to the director alone, so tournaments have to be set up either with undos allowed by opponents or no undos allowed. Hopefully this will be corrected one of these days.
