Running no mods?
Syxx_Killer ... very strange. Happened to me too last week. After I loaded the latest Environment mod. I noticed the dang white line back. So I pulled out the mod ... line still there? So I uninstalled all of PE and ROW stuff ... put it all back in and great ... no line since then.
(fingers crossed)
Hope that helps .... drove me nuts. I did a search under "sub outline", "white line" etc but couldn't find any of the threads I remember dealing with it pre-1.4.
I too thought either Dave fixed it in his mod or 1.3/1.4 got rid of it?
