I have recently installed DownloadStudio 6.0.6 and I am using it very successfully. However, I do have a problem in that regardless of how many downloads I schedule up, there is always 1 or 2 that stop at about 98 or 99% and fail to go any further. If I stop the download and then resume them, it will immediately go to 100% without downloading anything more and the files are complete.

Win 7 64bit Ultimate using IE8 with a 4Mb leased line. No proxy.

What do you think could be causing this problem?
