Yes, this has been pointed out. I'll see what I can do. Renzo (or was it
Jim? or both?) found the problem.

I think this is my lazy work with the GUI implementation of the pruning
option. I'll take a look!

I guess I agree with you even though I have never tried many different
move filter settings. Did it use to be: Always 2 + 3 within 0.100 ?

| 4) Settings/Analysis GUI: the tooltips on the analysis and evaluation
| settings dialogs sometimes persist instead of disappearing.  This makes it
| difficult to make selections, and I sometimes have to drag the window
| the screen to uncover the OK button so I can close the dialog and continue

with this

Yes! Quite annoying. It's a bug in GTK and not much we can do except
sending a big report to the GTK team.

| 5) Of course the biggest problem of all is the sometimes poor results
of the
| pruning net in rollouts combined with the inability to use the old
| evaluations at reduced speed.  2-ply rollouts performed at 50% checker and
| 33% cube speed have proven quite accurate and considerably faster than
| 100%.  2-ply prune rollouts, while faster per number of trials, are not
| proving as accurate, and have very high standard error rates, making them
| possibly unusable.

I'll try to combine the pruning and reduced searches in one build this
week. Cross your fingers. I'm also dreaming of redesigning the
evaluation settings dialog box, but that will maybe have to wait. I
guess it's more important that the thing work.
