Runtime under Japanese Windows

[clydog]

Does anyone know anything about possible system-wide problems caused by running an FM runtime on a Japanese version of Windows?

I work on a bibliographical project, based in the UK, but with international contributors. I've recently heard from our Japanese contributor that she's been having problems (she hasn't been very specific so far: 'the machine started to be annoyed by alterations of various letters and symbols, and the changes have become more and more extensive'), which she attributes to the runtime version of our database.

The runtime was created with Developer 5.5 under Win98.

Cheers
