[HTML]<input type="password" name="password" class="inputbox" size="19" alt="password" onkeydown="if(event.keyCode==13) return validate(this.form);" >[/HTML]

Modify it like this...
[html]<input type="password" name="password" class="inputbox" size="19" alt="password" onkeydown="if(event.keyCode==13) return validate(this);" >[/html]

And in the function validate(arg), insert 2 lines in the starting as:

arg.blur();
arg.disabled = true;

This will disable the password field, so no more event will be fired.

And use arg.form instead of the argument you were using earlier inside the validate function.

Also, when processing is done, you would need to enable the password field, if required.

After all this, I'm just wondering, why did you need that to test for the enter key while, its already like that a form is usually submitted when you press enter in the password field. If you had to apply you validation, you could do that in form's onsubmit event.
