Hi, Melusina, welcome to the Clumsy Scrollers Club.
I have just posted a thread about this. It's really annoying, though I don't know if I get annoyed with the Edge or with myself.
I thought there was a secret technique, like an initiation rite or something they taught you here when you became a Full Fledged Member.
But it seems no, it's just sweat, blood and tears, and perseverance.
Hmmmpf, Roma was not built overnight.
