Hi,
One can only draw a selection within the Main Window
and only when starting from a blank line.
ctrl and shift (accumulated) selection is not possible at all in the Track Browser.
Please enable mouse draw-selection (marquee) to be drawn freely!
And please enable multiple (accumulated) selection in the Track Browser!
These things are very important, not only for practical reasons,
but for keeping the computer conventions intact (windows anyway).
Thanks for considering,
D.
