Q: 

IE7 freezes after an aspx page with a highligted textbox and update panel posts back

I have an asp.net webpage with an UpdateProgress, UpdatePanel, ScriptManager and some form elements. When text is highlighted in a textbox and the form is submitted, the postback is successful but then IE7 is completely frozen. When I remove the updatepanel, the problem goes away.

Anyone knows a fix for this? Is there Javascript which unhighlights a textbox (a workaround?) ?
