duplicate downloads in Incomplete folder
 

Lately, using LWPro2.4.4 in Mac OSX, I have noticed that when a partially downloaded file begins to start downloading again (a day later), I see a duplicate of that file in the Incomplete folder. For example, I was up to 450MBs on one download with about 100 more to go. Suddenly there are two of them. One dated the day before and one dated today. I threw out the older one (without emptying the trash). The download still did not get completed that day and when I looked into the Incomplete folder the next day, there was NO file at all. I retrieved the one I threw in the Trash, and put it back, but so far it has not started up again since. (Actually, I haven't seen that file since on LW.)

This morning, I looked into the Incomplete folder and now I see two of another file I had started downloading yesterday and which had started to continue again today, then stopped. One file is dated today and the other dated yesterday.

I guess that my question is "what is going on?"
