Hi Paul,

Basically, when validation graphs are shown (bottom docked panel), the accept/reject dialog for refinement is partially hidden behind them; and then, if the user hovers the cursor over the "Maps" toolbar icon, most of the GUI goes bright green, for no reason that I can discern.
Cheers
Oli
