Controls dissapear after timeout

[Shai Leib]

My controls such as tabstrip and sometime panels seem to dissapear after a timeout of 30 min, even though my authentication time out hasn't. I ajax enable my telerik controls.

<

authentication mode="Forms">

<

forms name=".ADAuthCookie" loginUrl="Login.aspx" timeout="480" />

</

authentication>

Auth timeout set for 8 hrs just as a test.

<

sessionState mode="InProc" cookieless="false" timeout="480" />

Session set for 8 hr timeout also

I am using RadControlsQ1 2007
