atlas timer control with partial rendering -- HELP!

I have this code:

<

formid="form1"runat="server"><atlas:ScriptManagerID="ScriptManager1"runat="server"EnablePartialRendering="true"/><div><atlas:TimerControlID="AtlasTimer"runat="server"Enabled="true"Interval="5000"></atlas:TimerControl></div></form>

What happens is that every very seconds, I get a javascript alert on my screen that says "UNKNOWN ERROR".

I was just testing to see if a timer control would work with Partial Rendering turned on, like I've seen in lots of other examples... but I've tried this on 2 separate servers, tried re-downloading the framework and every time I get this error.

HELP! Any suggestions? I'm using the latest build of ATLAS.

ok.. well, I figured this one out. I guess if you don't have an update panel, then you'll get that error. You'll also get that same error if you have ANY "RESPONSE.WRITE"s in your page. It also doesn't like javascript on your page very much.

no fun.
