phpSysInfo doesn't work properly on some browsers. For example, on Internet Explorer 9, whenever I load the page, it shows an unstyled page until I manually change the theme using the drop-down box. Changing the default theme in the config has no effect.
Using Konqueror in Linux, the page doesn't load at all. It stops at "Loading… please wait!" and doesn't load anymore. This happens in dynamic mode. Static mode works fine.
Chrome & Firefox work fine, as far as I can see.
