SmartFTP does starts downloads again instantly after completing

I'm using SmartFTP 3.0.1016.7 and have a wired problem with on of our servers. When I do a download SmartFTP instantly downloads it again when it is finished. To get my download I have to make the file which is downloaded write protected as soon as it ends.

I havn't had this problem before and also I did no changes on our server. So what's the problem here?

Installing the newest version fixed the issue
