Possible bug in Mathematica 7 using ColorFunction

Problem: use of ColorFunction affects spacing of Greek characters in Frame label. Here is a simple example of the problem: SetOptions[Plot, Frame -> True, FrameLabel -> "Wavelength (\[Mu]m)"] Plot[y = x, {x, 1, 1000}, ColorFunction -> (ColorData["VisibleSpectrum"][#] &), ColorFunctionScaling -> False, Filling -> Axis] Notice the space between the Greek character \[Mu] and the m, causing the m to overlap the right parantheses. The space disappears if you remove the ColorFunction gradient from the plot parameters. Also, if you change \[Mu] to a standard character like m, the formatting looks perfectly acceptable. To be honest, I don't really understand the reason for the [#] & following the ColorData tag, but the gradient doesn't seem to work properly without it. Is my syntax correct?
