At last! Discotheque Of Doom ins running for me...

[aquaMat]

But - wait a minute !!!

Guess what....:

Just now - after I had written

Yes indeed....forget it

(below) I saw that AGAIN - the MODIFY button has vanished !!
Even though I hadn't accessed the page from my other Mac in the meantime.....  I actually hadn't been here at all in the meantime.

So what is that - it looks as if the

re-logging in

had solved the cause for one session only - so it means that that probably wasn't what CAUSED it, initially.

It can't mean that I have to re-log in each time I come back now, does it?
I always was logged-in

for keeps

on the old Mac - and the button never vanished there.  Mmmmh.

Sorry to bring it up again - after I had said

forget it

.      :o    8-)
