Buttons D and U

[Foxglove]

Buttons D and U were working on couple of tiles in 102 version, but in 111 we have to click on each tile manually, which makes rebuilding landscape longer and harder, is it possible to press D or U and drag mouse, to return old behavior of this button? Thanks in advance.

nothing was changed with these tools. Dragging should work, other wise -> file a bug report.

No, dragging doesnt work... only single click does. Do these buttons depend on pak? I mean, I did put old pak128 having edited factories, would it affect it?
What file has code about behavior of these buttons, after all?
Anyway I wrote a bug report: http://forum.simutrans.com/index.php?topic=8696.new#new
