The wierd behaviour is foremost in the behaviour of the mouse button.
eg. Right MouseButton pan is swapped with left MouseButton Zoom.
In the Hirachy Tree selecting an item is adding an item to the selection, like using the shift key.
I have to deselect items to have a single selction...
For that reason I'm not sure if it is only the mouse.
I've not seen anything like this in any other program.
And it is not always happenig.
But I have to close and open Spine every 5 minutes....
Nothing to hide in the log:
