[Bug-gnubg] Cubeful evaluation in Annotation window

Subject: [Bug-gnubg] Cubeful evaluation in Annotation window
Date: Fri, 7 Mar 2003 10:17:24 -0000

In the Annotation window the cube action is identified as "Cubeless", even 
though I have asked for a cubeful evaluation - the tooltip on the 1 2 3 4 
buttons reads "Evaluate play on cubeful n-ply"

In the example I have clicked the 3-ply button:
