Hi Guillaume,

The size, and thus the position vector of a uimenu may only be known by the
interpreter once it has been drawn. When run in a script drawnow is only
executed at the end of the script, when returning to prompt. Pause has the
effect to trigger drawnow (try with drawnow, it should work also).
Does ML have the position right before returning to prompt?

As for the warning when you try to set an incorrect value for position, it is
due to a recent cset that added input checking:
