Thanks for the bug report.

I just tested it on a Windows 2000 machine and a Windows XP machine, and found that bandwidth limiting is working in the current version (v5.1.2.0). As Brent mentioned in an earlier reply to a user, its not as accurate as we'd like and we'll improve that in an upcoming version. But it is working for us here.

As a test, turn off the limit bandwidth checkbox on the Job Queue tab in Download Files mode in DownloadStudio. Start downloading your 500MB file. Observe the speed and the bandwidth graph. Now turn on the limit bandwidth checkbox and set the limit value to (say) 80 KB/sec (you can change it dynamically to any value whilst downloading is taking place). You should see some immediate throttling of your 500MB download. If not, please email us before and after screenshots to support [at] conceiva.com and we'll check it out further for you.

Best regards,

Paul
