I have a VB.NET client that uses the Resco zip library to download a zip file from a WCF service and extract its contents to a specified folder. This operation works flawlessly if the full path of the specified folder starts with a drive letter. If a UNC path is used, not only do the files not get extracted, but no error is thrown either. It's not a permissions issue because the same problem exists even if I use a UNC path pointing to my own local drive (\\jon\c$).

Any ideas would be greatly appreciated.

UPDATE: Never mind - we have an older version of the Resco library which is known to have this bug.
