Problem with Javascript or Permissions? - Joomla! Forum - community, help and support

hi everyone:
i installed  joomla 1.04 on apache server (hosted hosting company).  seem have problem though had when tried out "mambo." 

everything seems work ok (adding modules, components, moving around admin section, etc.).

the problem:  when try change category name, edit existing faq/page, not able click "save" or "apply" button (in  fact have use button on browser proceed. buttons "hightlight" thats it.  notice if click edit previous post (that came program), never see text "edit" it, 2 blank boxes. can't change titles, categories, edit text, etc. have installed several of components/modules (including tinymce).

i checked both dreamweaver 8, cuteftp, , beyond compare 2 make sure latest files (and of them) on server. also, joomla says permissions set ok.  trying make changes "super admin."

lastly, able use joomla demo these things (so think know how it).
