If I change the setting "Edit" -> "Mouse Settings" -> "Camera View" -> "Paste Shader Natural" to SHIFT + AUX1, I cannot use the Paste Shader Natural functionality.
AUX1 is the button used for 'go back' in browsers. It works in other programs.
It seems to be the same issue for AUX2 ('go forward').
I also tried changing other MMB bindings to AUX1 (Pick Shader, Paste Shader Projected) with the result that they did not work.
Also tried with another mouse, with same result.
If I set it to something else, e.g. shift + right mouse button, it works as expected.
On Windows 10, 64 bit.
