Try going into Tools -> Fonts and Colors, change nothing and click ok. It's sorted out problems like this for some people I know. I think it makes VS reapply the stored color settings.

Many thanks...you're a .. erm...Saint! Worked like a charm - not sure when/if I ticked that box, but it looks much better now.

It's true that this will fix the issue, but it also turns off a very useful feature of ReSharper. The issue here is that most colour schemes out there don't take advantage of the additional colourings that R# adds to VS. I took the time to choose colours for each of these in the Options->FontsAndColours section and am very pleased with the results.
