Question : Browser Window Opens at start-up after upgrade to OS X 10.5.7

I upgraded for 10.4.11 to 10.5.7 last night. (was easy)  Now that I am on OS X 10.5.7 Leopard, when I turn on the laptop (Macbook Pro) and login a browser windows opens showing a page from the library folder (//library/printers/xerox/. . . . something or other).  The page is in German or something (I speak English) .  Booted several times and the browser/page shows up every time.

I am thinking that there is some residual left in a startup folder somewhere that the upgrade install did not clear out or something like that.

Where should I look within the system/files, etc.to see what could be causing this?

System prefs > accounts > login items shows your login items.

Also have a look in Library > startup items
