Thanks for explaining the complexities. A few more questions:

1. Does that mean Sergey's hack to mfs.c is not a permanent solution?
I've made the changes but am waiting for my Foxpro users to test it.

2. Is using smbmount to access the Foxpro files from Dosemu a valid way
to get around the locking problem? I suspect it will be slower but
anything else?

Thanks again.
