@Guest: I have the same issue currently using the 3.4 ALPHA build 902.
My system is Windows XP Professional SP3, 2GB RAM, and I do a silly tip to make it finish right away. Since I feel comfortable using hot-keys, I select my 100% non-finished file, press shift-O to stop it, and immediately shift-S to start it, and like this it finishes right away.
Yeah, I would say is a bug...an annoying one!
@Alex: Can you please do something with grid columns? Whenever I click on
Downloaded to sort them by percentage, it does not obey my request and on top of that, it does not even sorting them properly. It mixes up finished files with unfinished ones, without making any sense.
The same goes for
Size and
File name. By clicking on
Size, and then click
File name to sort them out, I have to press it one time to "restore"
Size's default positions, and one time again to "restore"
File name's default positions.
Also, occasionally, from time to time, every single data grid on FDM needs double-click on column separator to enable resizing for some reason. Now it works fine, but it had happened a lot lately. Don't know how to reproduce it though

P.S.: Is there a bug tracker somewhere for FDM and I haven't seen it? It would made our lives a lot easier like that you know...
