First I have to say Multiget is a great tool and I really like it.
I just found a small bug to help you improve it.
When I download a big file of 1.2G with 2 threads, the green progress bar under the menu bar be comes too long and it overpasses the frame border. And it even passes the scroll bar's controlling range. So I'm not able to see how much it downloads from the graph.
Hope this info is useful to you!
And again, your soft is cool!
And I upload a screenshot of this bug here
wow, you have quite a good internet connection.
that isn't a "progress bar" but a speed indicator. Basically your speed is too fast (681KiB/s) so it's always full :)
