Hi all,
We use NPM v9.5.1 and i've just upgraded my machine to Windows 7. Now, when viewing maps I get the following;

It seems that text is ok, but all images are almost in a sort of 8-bit colour gradient. I've created a brand new map, (shown above) as a test and it is still the same. In Atlas it looks perfectly fine. This result also occurs when using Chrome as well as IE8.
anyone got any ideas? It's the case with all our maps..
cheers,
Alan
