Recenter data only works once

[GoogleCodeExporter]

0) Open some file (olive.csv).
1) open a xy scatter plot
2) choose identify
3) pick a point - now press "Recenter"
4) pick another point - now press "Recenter" - it will not move


(and in general, I'm not sure why this is not in the scale window, but I guess 
it could be either way)



(I'm working on windows 7, ggobi 2.1.8)
