I think that it will be more consistenly in terms of GUI if tooltip will disappear as soon as user moves the mouse more than some number of pixels. Let say, I have several rows with long text inside and when I want to see another row that below currently viewed, then I have to move mouse off the column then move it back... It would be good to clear tooltip as soon as user moves anything (mouse, keyboard, whateever)

Dear Vladimir,

I see, that I cannot avoid ItemTipBehaviour property. (It is not obvious when to display itemtip again after hiding. When cursor gets over this item again?)

But, now you needn't move the mouse cursor outside the column! If cursors get over an other row, current itemtips disappear, and the new itemtips appear!
