...these two do not seem to work as well together as I had hoped. Maybe I
have the wrong versions. This is somewhat frustrating. I have worked with
Proto and Scriptaculous before and they worked well, but I can''t seem
to get
both FF2 and IE6, IE7 working with both Ajax capabilities and Scriptaculous
effects using Prototype and Scriptaculous.
I''m including my versions below. I can get the Scriptaculous Effects
to
work now, but not AJAX (proto) inside of FireFox 2. Both effects and
ajax.updater, etc work within IE 6
-Mark
Here''s the version of Prototype I''m using, followed by the
version of
Scriptaculous:
