Problem accessing attached libraries in Oracle Forms

We have downloaded your SFTPDRIVE 1.7.9 product and are testing it. It works find when accessing the drive in Windows Explorer. However, we are having trouble with it when using the drive with Oracle Forms. Oracle Forms uses a registry entry 'Forms60_path' indicating the path for attached libraries Forms needs. We are using the drive letter defined in SFTPDrive as part of the path. When opening an existing Form, Forms loads for about 3 minutes and then displays a number of attached libraries it cannot find. However, the libraries appear to have been attached correctly.

Can you help?

Thanks.
