In the old interface, I could select all or parts of the download urls with the mouse-middle-click paste e.g. into an xterm

In the new interface this only works for the first selection attempt. After that, in that line are no corrections possible, once the full line is selected, the url becomes "draggable", but it's apparently not in the X selection.

I can get back to the initial state only by re-entering the dialog.

Another weirdness is double-click: This selects a single word in the url, but the whole url appears selected (and is in the weird non-correctable state, too). Triple click works, i.e. selects the whole url and selects it opticially (but is also in the non-correctable state)
