Hi Michael,

thanks very much for your fast response and sorry for my delayed reply :-)

Appears it has something to do with multi-monitor configuration: when the MoI window spans multiple displays, then the mouse-wheel zoom focus works as expected - as long as the mouse pointer is on the primary display, only!

However, for efficient object editing, I maximize the windows that so each view is on a separate display, and so I need to move the mouse pointer to the other displays to edit objects and then mouse-wheel zoom focus doesn't work reliable any more.

As mentioned, the "Area/Zoom/Pan/Rotate/Reset" buttons always change focus as expected on any display. Would it be possible to use the same detection mechanism for the editing area? Or make it configurable in case it brakes Windows or OSX?

Feedback is highly appreciated!

TIA and best regards

Bernhard
