If you have SS Extremes it is possible to copy the file "Questviewer" from the root menu of SSE and then overwrite the "questviewer" file in SS 2008. This does away with the problem described by K Jack above. A word of warning though, first copy the SS 2008 file to a "new folder" before you overwrite. That way you can, if you want to, replace it. An easy way to identify the two files is that the SSE file has the symbol of a green triangle beside it and the SS2008 file has a symbol showing a mans head beside it. As Johan (JoMach) has also said this allows you to go onto "Mutiplayer" as well. The picture below shows the SS2008 file in the place I copied it before the overwrite. The file appears exactly the same in the root folder of SS2008.
