Scott,
You can email me vivek [at] unleashnetworks [dot] com.
If possible, can you transfer a file containing non-confidential data between the two shares ? You can email the capture to the above email address. That would be the fastest way.
We tried to simulate a XP share here, it works fine.
If you are looking at icons or bitmaps, SMB seems to transfer the image over for constructing the thumbnail, so that counts as two. If there are other file types appearing twice, it is probably a bug.
Regards,
Vivek Rajan
