Nodes Editor - Can't see lines

Hey,

I can barely see the lines between nodes in the nodes editor and that’s only when moving the nodes about - it seems to be a very faint grey, 1 pixel wide and almost the same shade as the background. I’ve seen other screenshots and the lines are bold. Why is mine different?

Here is a screen shot with nodes that are linked but you can see you can’t see them: http://img19.imageshack.us/img19/6435/53393734.jpg

Sorry to bump this but does anyone have any solutions?

Try to set different colors for the background color and the lines in the theme editor window (I think you cant see them cause they are both the same gray.)
Or else try another version of blender or recompile it if you are using a SVN version.
