I'm sorry about that, some time ago I made a positive review of your program,
even wondering how long BookUp could have kept it's high price.
You might wonder why not even I have registred it.

Well, after using it a bit I had the feeling it was an unfinished work. I think
that the inteface was so-so in series 3 and at some point there were even some
resolution issues: on my screen I could not even have a decent board to look at.

Now the new version I just donwloaded is much better in terms of itnterface.

I has one big bug at least: when you assign an evaluation sy +/= to white
position after a given move stepping back/forward by half move the evaluation
changes sign (graphically) to =/+.
I agree that some prorgams consider the score relative to the side you look at.

But signs like +/= and =/+ are ususally absolute, and indicate a slightly better
position for white and black respectively.

Other wanted features are:
- I would prefer to see the list of recommeded moves ordered from best to worst
- navigation button for stepping forth and back
- when you press the arrows the program should move in the movelist by
half-moves and not reset the game input
- I would also love to see also a feature (to be eanbled or disabled with a
flag) to autoadd moves to the tree when the user inputs new moves

Franz
