I have a browser functional difference using RadToolTip in template columns in RadGrid. I have successfully used these tooltips in IE7 and FF3, but I recently upgraded to IE8 Beta 2 and now the tool tips do not display when hovering above the tooltip-ified columns. They do display when you click and hold the mouse button down on the tooltip-ified element in IE8, but shouldn't the behavior be similar across browsers?

All that being said, this could be purely a Microsoft problem and Telerik may not be interested in trying to get all their tools 100% compatible with beta browsers. But if Steve Ballmer and Co. are changing the rules, I thought you might like to know.

IE version showing this behavior is: 8.0.6001.18241

Code to reproduce the problem is below.

ASPX:
