Quite so, my error. I don't know why it worked here in my test-case, I can't make it do it again!

Blaim that one on cut&paste - don't test for "is.dom" but "e.preventDefault".

The textselection shouldn't happen since the draglistener does a cancelBrowserEvent() on mousedown and mousemoves (I think the latter is superfluous - it is here at least).

I haven't made any changes to dragevent.js, all my checking/testing is done on mouse.js. If I remove the cancelBrowserEvent() in dragevent's onmousedown I too have the textselection bug.

I will try to make this work during the next few days (I've given up on a simple solution - or at least an easy-to-find one). I'll let you know what I come up with (in DynAPI-dev instead).
