In reply to myself.
As its IS Sunday I don´t expect an answer right away.
And instead of just writing "please help" in every thread available I tried to use the search function.
Anyway, whilst waiting I´ve tried this:

Nope, didn´t solve the problem.
And I logged in on another, fresh, account but to no avail.
Still, just the hour glass and then nothing. Just a computer that I have to reboot. Oh, I also tried three different anty-spyware programs just to be sure. But no, still nothing.
