IE - very strange problem

Hi, I have been advised that the homepage http://www.predict.ch/ does not work with some browser/OS combinations. The problem seems to be the following code's lines: $result = mysql_query($sql,$db) or die("Please check your query and try again"); $db is defined in an included file: $db = @mysql_pconnect("localhost","xxx","yyy"); @mysql_select_db("predict",$db); and $sql looks so: $sql = "SELECT " . $HTTP_SESSION_VARS["language"] . "_title as title, " . $HTTP_SESSION_VARS["language"] . "_abstract as abstract, " . $HTTP_SESSION_VARS["language"] . "_content as content " . "FROM news where showIt = 'TRUE' ORDER BY published DESC"; with $HTTP_SESSION_VARS["language"] = table_read("language"); The most visitors get the index.php4 with the query correctly shown. 2 people (Win98 or Millenium/IE 5 or 6beta) get the die procedure: "Please check your query and try again" and I really do not understand why. I am really confused and would like to solve this problem. Could someone help me? Greetings, christian
