Mac/Windows INDD files are totally compatible. It’s the version number you need to be aware of, not the platform.
Speaking of which, InDesign 5 is CS3 and INDD files are not backward compatible.
Hi Bob thanks for your reply. I did mean InDesign CS5 and the thing that most concerns me is the question of fonts which I understand may cause issues (as usual). When the pages were originally made the fonts are a mish mash of different formats, OpenType, TrueType and crucially, Type 1. Is it ok to carry on or will there be problems?
OT & TT are fine… Postscript may cause problems…

The same issues with fonts remain. Mac TT and T1 fonts will not work on PC (PC TT fonts will work on Mac, though, so it's possible some of the TT fonts, if purchased in the last few years, are really Windows fonts sold as cross-platform), nor will .dfonts. The easy way to tell if a font will work is to look at the file size in Windows. 0k means it was a Mac font and will need to be replaced.
