    I have a button in an updatepanel, with a RadProgressManager/Area thing going on. The Area is set with RegisterForSubmit="false" and the button has an onclientclicked="showProg", which is a function which calls getRadProgressManager().startProgressPolling();

    First click shows the progress bar, but when it's finished the progress bar disappears and then reappears very quickly (it should stay gone).

    Second click shows the completed progress bar from before, for the correct duration, then hides it (and it doesn't reappear). (it should show the correct progress sequence).

    Subsequent clicks behave as the second.

    public partial class Default : System.Web.UI.Page
        protected void btn(object sender, EventArgs e)
            var prog = RadProgressContext.Current;
            for (int i = 0; i < 10; i++)
                prog.PrimaryPercent = (i+1) * 10;
                prog.CurrentOperationText = String.Format("Doing step {0} of 10", i + 1);
            prog.OperationComplete = true;

    (I would attach the zipped solution, but the attach file dialog only permits images)
