PHP3...load button netscape 4.5

Running php3 on win95 with mysql...little problem with the browser, Netscape 4.5 One page is a script that queries the database and produces results sorted by catagory. The user selects the catagory (the url is constructed using php_self and a query_string), the database is queried again and the specific info about the topic is displayed on the page. After the first query the Netscape load button dims after the page is loaded, after the second query, the button refuses to dim indicating the page is still loading and it will not manually click off...however, the status bar at the bottom indicates the page has finished loading. anyone know why this is happening. Both pages are identical except for the info displayed and one page's url contains a query string, is there a fix... ken
