>Recently, I started a thread about avoiding the onkeypress to be affected by the auto complete, which is enabled on textboxes. However, I cannot get this auto complete to appear on any on my browsers now. Anyone knows the rules which may affect the enabling of that option?

To be more precised, this is only applicable to Internet Explorer and Firefox. Something generic has caused those browsers to avoid using the auto complete. I just tested with Chrome and it works.
