HTML_Menu problem with special URL's

First, Alexey (and Ulf where i found Menu 3 for the first time), thank you so much for this excellent piece of software. I am using it for more than a year now and customised it to my needs. Nevertheless (now using Pear HTML_Menu 2.1) i encountered a problem which i can not solve myself. I have a menu that looks like this: $data = array( 'Presse0000' => array( "class" => "newsmenu", "url" => "/", "anchor" => "", "target" => "", "title" => "Home" ), 'Presse0001' => array( "class" => "newsmenu", "url" => "/presse/schlagzeilen.html?start=0&amp;count=5", "anchor" => "", "target" => "", "title" => "Schlag-<br>zeilen" ), 'Presse0002' => array( "class" => "newsmenu", "url" => "/presse/schlagzeilen.html?start=5&amp;count=5", "anchor" => "", "target" => "", "title" => "Schlag-<br>zeilen: Seite 1" ), ); In this case i use the 'prevnext' style to build a menue. I use "var $_urlEnvVar = 'REQUEST_URI';" (also in function HTML_Menu) instead of PHP_SELF because i use mod_rewrite. When the current URL is "/presse/schlagzeilen.html?start=0&amp;count=5" the previous URL shown in the menue is "/" which is correct but the next URL shown is not "/presse/schlagzeilen.html?start=5&amp;count=5" as it should but again "/presse/schlagzeilen.html?start=0&amp;count=5". As soon as i change the url in 'Presse0002' to, lets say "/presse/schlagzeilen_test.html?start=5&amp;count=5", it works as expected using 'prevnext' but i can not really live with that. Furthermore, these URL's are correcty recognized when using $menu_type 'tree' or 'sitemap'. The current URL is correctly recognized but (to my limited understanding) the node url does not seem to be recognized when i try to use $menu_type 'prevnext' in this case. I hope, somebody of you can show me a way how to use the above mentioned URL's from the menu hash with $menu_type 'prevnext' successfully. Thanks in advance and best regards, Marcus Merz
