| 3) Move filter for Tiny is still selecting 8 candidates, 0.080.  Seems

| that gave very good results with 5 candidates, .100.  OK nevermind I just

as well
| so I guess that's how it has been...I thought it used to be 4 candidates.

'Tiny' is now redefined to 5 candidates within 0.08.

| 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
| using the program.  This has been going on for some time, not just
with this
| latest build, but I suppose it could have something to do with my graphics
| card if noone else is having the trouble.

Can't fix.

| 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.
