Download file 0kb from Mac HD to QC with RDC v2.0

Operating System: Mac OS X 10.5 (Leopard)
Processor: Intel

Hi,

We are using QC via RDC from Mac Os computer.
I am testing the new version of RDC v2.0
I am experimenting an issue :
from QC, you can attach files. The download from mac os HD is failing : the weight of the file attached is 0 kb.

It works fine with in RDC v 1.0.3 and it works fine with other tools like Excel and RDC v2.0.

I have requested to our support team; they answered there is no need of adjustment of the Windows server hosting QC and there is no mean to adjust QC for a RDC mode.

Is it an RDC v 2.0 issue ?

Thanks for your help
