It happens to me that, when I have tabbing on (even if there's only one conversation window), the scroll bar gets fucked up. If I try to scroll up, after one second or so, the bar returns to the bottom of the conv, no matter what. This happens both when I scroll holding the scroll bar, clicking the up arrows or scrolling with the mouse. So I can't read stuff that have been said earlier

. When I turn off tabbed conv, this doesn't happen.
