Firefox bug? Getting an Alert message to popup in an UpdatePanel

I can use the following code to popup a MessageBox inside an Update Panel...

System.Web.UI.ScriptManager.RegisterClientScriptBlock(this.Page, typeof(Page), "myKey", "alert('ALERT MESSAGE!')", true);

The problem is that in Firefox none of my drop down boxes work after the message has gone. They appear but when I select an item it doesn't change. It seems to work fine in IE.

Any ideas how to fix this or perhaps another way of producing an alert in an UpdatePanel?

Can you see when you do a VIEW SOURCE on the Page..

also maybe try...

For some reason that doesn't work for buttons inside an UpdatePanel. I get...

Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.

Details: Error parsing near '<Script>alert('Hello'.

ScriptManager.RegisterStartupScript(Button1, typeof(Button), "scriptkey","window.setTimeout(\"alert('test!')\",0);", true);

with window.setTimeout, the dropdowns will work properly after the alert.
