I've just tested a couple of things out in SE and the only way I can emulate this behaviour is with the standard moog knob from the controls menu. The corresponding text file reads:
type animated
frame_size 48, 45
mouse_response rotary
; extra space at: top, bottom, left, right
padding 13, 7, 13, 4
This knob will respond vertically if you pull up and down after clicking it but switches to rotary if you circle the mouse. My own knobs do not exhibit this behaviour and only work in a vertical fashion, their text files read:
type animated
frame_size 24,24
mouse_response vertical
transparent_pixel 0,0
Hope this helps you novaflash.
