Problems with update panel

Dec 20, 2012 at 3:04 AM

I noticed that if there is an update panel refresh on the page, the captcha control will always return false even if the correct values are typed in.  After failing, through a full postback, then the captcha control will work properly.  I have an update panel that relates a state dropdown to a county dropdown.  Each change on the state dropdown refreshed the county list through an update panel postback.  This caused the captcha control to not work correctly.  When I removed the update panel, it worked fine.  Is there a way to get the control to work with an update panel on the page?  The captcha control was not in the update panel.  The update panel only contained the state and county dropdowns.
