I created a sample dropdown containing states and it worked fine for me.
The only difference is I didn't use the Page.IsValid

Here's the code (server):

      private void CustomValidator1_ServerValidate_1(object source,
System.Web.UI.WebControls.ServerValidateEventArgs args)
      {
         string s = args.Value;

         if (s == "IL")
         {
            args.IsValid = true;
         }
         else
         {
            args.IsValid = false;
         }
      }

Hey Rick:

I am working on a project where I am experiencing the same exact problem.
For test purposes I don't fill any form fields - including the text
boxes.  All the RequiredValidation controls fire for the missing values in
the textboxes and my CustomValidation controls fire (using my work-around
code on the Server and the client.) When I add values to the textboxes,
the error message disappears when I tab from that field (IE60) but like
you I can no longer clear the CustomValidation error msgs from my
dropdownlists.  Looks like a bug to me.  I am using Beta 2 (1_0_2914_16).

If you hear anything please let me know.  I will do the same.

You would think that this should be an easy thing to do!
