anytime i try to mount any iso or bin/cue file, dosbox says the drive is mounted, but i cannot access any files on the image file.

"Z:\imgmount D [iso or bin/cue file] -t iso
MSCDEX installed.
Drive D is mounted as [iso or bin/cue file]

Z:\D:

D:\dir
Directory of D:\
File *.* not found."

does imgmount work on os x, or is there something else i need to do?
i am running dosbox 0.63 on os x panther 10.4.1
