SFTPDROP bug still exists

I've got SFTPMSI.exe version2.5.1008.26 installed on Windows Vista Business edition. I've tried all the recommended uninstall restart install latest restart, etc. I've even tried running the installer with "Run as administrator" The problem persists. Dragging a file from SmartFTP to desktop or any other location results in a SFTPDROP folder being created. Will you help please?
