Can't change measure numbering in SLE

Double-clicking over any bar number while in editing mode should allow you to renumber that measure (see Notion SLE User's Manual 11.19), but that just doesn't work for me.
Could you please give it a try and see if it's working for you? Maybe it's an SLE bug...
