When I drag Stanza.app (beta 18 build #1:413) from the mounted drive to the applications shortcut (or to any other folder) I get the following error:

ERROR
An error occurred.
The operation couldn’t be completed. (OSStatus error -36.)

However, I can run Stanza from the mounted drive and it works fine. Here's the system info from Stanza:
