Hi Sean,
I've also had this problem with OS 9 and e-smith 5.1.2.
The workaround we've come up with is to save to the local hard disk, then copy them to the ibay. An extra step, but it does work to get the files there.
I've been looking for a solution to this for awhile now. This looks like the best I've found here so far (Thanks to Mr. Maggard):
