Popup on a popup table jittery in IE8

I am using a popup with style set to views table. When moving between rows I get jittering (rapid show/hide) of the popup in IE8. Its fine in firefox.

I thought it was probably because the seperating line between rows was counted as leaving the element.
Not sure if its the right way to solve it, but I thought a slight delay on shows after the initial show (ie not setting var popup-time to 0 would prevent any of this kind of jitter without giving noticable delay to user. In view_popup.js. I created a var popup_time_min = 100 and set popup_time = popup_time_min instead of setting it to 0.

I am not a experienced js programmer and only spent a little while coming to understand the code so I wont be suprised to be told this was the wrong thing to do. But thought it right to bring to the attention of the maintainer
