We have a page that has a RadGrid and an AjaxManager linked to it so that it looks seamless when they attempt to edit, add and delete rows in it. The grid loads with one row in it that has 2 time picker columns and 1 date picker column. When the user clicks edit to edit the row, the loading panel spins briefly, then freezes and IE starts using 100% of the thread. We've duplicated this in both IE 6 and 7, but haven't really tried any others yet.
Does anyone have any ideas as to what might be causing this?
