Scrolling in long results is not very intuitiv

[TobiasNx]

When processing a long result, the result window is expanded accordingly, but scrolling is some kind of annoying. When moving the curser on the result window, one cannot scroll, one has to move the curser beside the result window then it works. Scrolling should work beside and over the result window.

Also the result window size should be limited and one should scroll within the result frame.

This might be connected to #224 and why this is slow.
