SCCM 2007, BITS and Packages with Hidden Files

Hi all.  We just encountered an odd issue at work earlier and I haven't managed to stumble across any references to this issue anywhere, so I'll post a new one.
 
If I have a package that contains hidden files, my Windows 7 clients fails during the package download to the local cache, specifically, during the validation phase of the download, just before it launches.  I've tested this several different ways and so far it's always come down to whether or not the package has a hidden file in it as far as whether or not the download succeeds or not.  If you want to test it, in my package source folder, I created 2 text files with a few characters in it to give it size and a dummy batch file to use for the Program.  I hid one of the text files, then distributed and advertised.  On the Windows 7 machine, the advertisement alert came up and it proceeded to download the package to the local cache, then during the validation failed.  If you go back and un-hide that text file, update the DP and wait for the package versions to get lined up, then re-run it on your client, it works.
 
Am I crazy?!  I don't recall ever having this happen on SMS 2003 or other company's SCCM 2007 systems before, but now I'm wondering if I've ever tried to move a hidden file through BITS on Windows 7.
