+
+To reproduce:
+1. download login2.aspx, login2.ascx and web.config
+2. start xsp2 in the directory with the files
+3. visit the server page
+
+This bug occurs every time the page is visited.  I'd love to help debug it
+but I can't figure out where to start given that no values are displayed in
+the stack trace.  I only got lucky and figured out that the
+RegularExpressionValidator was the cause by trial an error, removing wigets
+from the page.
