Windows XP has a limit on the total pathname length of 250 chars, not on the filename length. The pathname includes the starting "C:\" and null and the end of the path.

Thanks to both you (dave_59) and Taz1984, I forgot to rename the vho file back to its original name, after doing this all files are now found if I move the sim project to say c:\ms\ to minimise total pathname length :-)

Many Thanks

Lee
