How to get EPS with transparent background in Frame?

[Tori Muir]

Am preparing Illustrator EPS graphics for a Frame 9 user (triangle-type 
'warning' symbol). She needs them to have a transparent background, so I 
am saving as EPS with TIFF 8-bit  color preview, and transparent. 
Nonetheless, when she imports them they have a white background. I have 
tried saving as CS2 EPS, and Illustrator 10 EPS, with the same results.

How does one get Frame 9 to acknowledge the transparency in an EPS file?
