trouble signing in from Opera on a Nokia 770 internet tablet

I tried signing in to Zoho Writer both from zoho.com as well as from izoho.com, but in both cases I cannot get past the sign-in dialog. When I enter my id/password and press the submit button, the little text next to it changes to "signing in ...", but nothing else happens
