Queue works but not not with adjusted number of downloads (adjusted 4, downloading 4 to 10). Settings cannot be shown/changed (empty window) when several downloads running. DownloadManager opened with menu in status bar shows empty window while downloads running. DownloadManager window opened with icon in task bar only shows one progressbar while downloads running but nothing else. If there are e.g. 5 downloads running and 20 done, I cannot delet the completed downloads by using the menu in the status bar. I have to wait until most downloads are finished. So I get more and more lines shown in the status bar. I have to say that the S3 Downloadmanager works fine when I download not more than 3 or 4 files at the same time. But that is not the reason why I use a DLM. I want to start 20 DLs and keep my system working. For me there are more cons than pros. Sorry.
