I'm loading a tooltip on demand using RadTooltipManager.  The tooltip displays fine, but throws an exception in javascript when it is closed.  I implemented the centering javascript code to center the tooltip in the screen (as in the Telerik example), and that seems to be what is causing the problem.  When I take the call out, there is no error.  But then, my tooltip isn't centered.  Anyone have any ideas what I'm doing wrong?

Thanks!

I upgraded to the latest version, and it appears as if the Web20 skin has changed. I cannot see the text in the grid as the background is white and the text is white. Here is my grid. Is there something I need to add to have the text black so it shows up?

Thanks,
Susan
