Jabber file transfer option greyed out in Windows client when trying to transfer to a Mac client

When the Mac Jabber client is set to an Away status only (regular Away or custom), the file transfer option is grayed out for users on Windows Jabber clients. However, the Mac Jabber user, whose status is set to Away, does not have the file transfer button grayed out and can transfer files successfully. This same situation does not occur when the Mac Jabber user is in the Available or Do Not Disturb statuses.

This is ONLY with the Mac Jabber client while in the Away status during an active chat session with a Windows Jabber user.
