Dear All,
I have a variety of different (Ordnance Survey) TIFF Raster images (1:50K, 1:25K, 1:10K) which lose their Colormap information when loaded into ArcMap 10. 

Instead of being 8-bit / 256 colors, they just appear as 1-bit binary (speckled black pixels and a legend of "0 White").

I've tried this on a number of PCs, but none will load correctly.

Any ideas on what I'm doing wrong? Or whether it is a Windows issue rather than an Arc bug?
Cheers,
David.
