Random command behaviour

Suddenly my Rhino started to act really weirdly. Out of nothing it decides to make commands related to layouts.

eg. Command: _-Layout
New Layout Name <Page 2>: _Enter
Width in millimeters <215.9>: _Enter
Height in millimeters <279.4>: _Enter
Detail Count (0-4) <1>: 4

Everything happened without any input from my side and is causing the program to switch between different layouts and view settings.

Hi Jan - sounds like a script or macro ran - is it just happening any time, at random?
That sequnce is what this button runs, in the Drafting toolbar
