Hello,
I'm currently using amuled + amuleweb 2.1.0 Linux (on slackware current with VIA C6) but the same behavior appeared in amule-cvs from mid of december.
I get all the stuff working (amuled+amuleweb). Using IE or Firefox 1.5 linux works just fine. But when I try to use Firefox 1.5 win32 I allways get back to the loggin page.
Ok lets detail a bit: I loggin and get the interface with the topbar. Clicking on any of the topbar icon gets me to the webpage (let's say ttp://meeni-itx:8181/stat_graphs.php ) but instead of the graph status, the webpage displays the logging dialog.
The problem appeared both with default and chicane templates.
