When I'm logged in as a user and move the mouse cursor over the "downloads" link the image is replaced by the highlighted "services" (button_services_on.png) image while my "filemanager" image is replaced by the highlighted download image.
Being logged in as the admin the filemanager link has the same behaviour while the "users" image is missing even though the button_users_* images are the /web-admin/images folder like they're supposed to.
It seems as though I somehow messed up that left frame or something even though I swear I didn't touch it during my ventures yesterday.

Anyway, as I'm assuming that nobody else is having that issue I'd love to hear how I can get that frame back to normal.
Thanks,
Christoph
