box selection changes view

[HoWil]

Hello,
The "view position" is changed when I use box selection "Shift-b".
Is there a setting to switch this off?
Please see the attached screenshots to get an idea what I experience and am looking for.

I cannot confirm this behaviour. Here is the relevant callback function and it only alters the selection but not the camera position.

Maybe there is somewhere in a wb a special mode that automatically aligns the selection with the center of the 3d view.

It sounds strange but you should also make sure that the viewer's camera really doesn't change. You can add a reference object which you won't select and this must not move then or print the camera settings with: Gui.ActiveDocument.ActiveView.getCamera().
In the past I have observe similar issues when a model was weirdly broken or the OpenGL rendering didn't work like expected.

This behaviour has been reported before, although I cannot find the post. It seems to depend on the mouse model. Which one do you use?

It's touchpad navigation... Same as in the report... Thx for digging it out.
