[Elecraft] P3 f/w 1.26 slow to respond to span changes

[Graham Kimbell G3TCT]

Hi all
Recently I updated my P3 f/w from beta 1.08 to 1.26.  Just noticed that 
changing the span has now become rather clunky - it only changes about 
twice a second, whereas before it changed immediately.  I've reloaded 
1.08 to check and this seems to be a feature of v1.26.

Any chance of getting the quick changing span back?
