Hello, Gentlemen, As everyone knows, you can zoom and pan using the mouse wheel. But on one of my PCs, (under W8.1), this is only possible if the mouse cursor is in the (X>0, Y<0) area of the screen. Elsewhere, it is ignored. I understand this is certainly due to something wrong in this PC, since everything is quite normal on others, but I would like to know whether somebody has met this problem before, and what he did to correct it. And of course I have tried different mice! Regards.

There have been similar reports on the mailing list, but I don't find any of them reported as issues. The notion of it being effective only in the X>0, Y<0 area is pretty seriously weird, since that's often a section of the screen not aligned with the screen's axes.  Are you sure about that part? Also:  check Edit/Preferences/Mouse; ensure that it's set to the OpenSCAD preset.
