Uploads restart in Transfer Queue

More often than not, I transfer very large files. Frequently, but not every time, after the upload in the queue finishes, SmartFTP immediately starts the upload again. Doing so overwrites the upload that just succeeded. Once in this state, it will do this infinitely. My only recourse is to use another client to accomplish the upload. This happened under 1.x and it just happened again under 2.0. Here is my About page.
