Did you contact ChessBase about the problem? They ought to know how many users are affected. If the problem persists, you should ask your dealer for a refund and return Fritz. > KK also reported that some other people has/have reported that bug to him and >all he knows is that the tree could NOT be fixed/restored once corrupted.

He also told me that Chessbase >now has added an option under the Book menu, called "Restore Old Book", though >he wasn't clear about what it does exactly? Poor KK sometimes mixes things up ... After all, he's just a Komputer ... There's no "Restore Old Book" feature but an "Import Old Book" command to convert old books from Genius and Rebel into Fritz trees. But don't hold your breath, I found it to be useless for any real purposes. Or maybe he was talking about "Restore Old Bug"? > Mabe restoring the book to the state >it was before getting corrupted, from some of backup? Your idea with doing a backup is fine, trouble is you need enough space on your harddisk for a second copy of each tree or a "serious" backup solution, e.g. DAT streamer with backup software etc. > As for you suggestion, I only have ONE computer.

I don't know if it's a known "bug" ... I have done much work with trees in Fritz and ChessBase and never encountered it (I have built trees up to 3.5 GB big) ... How much RAM do you have? I have >64 MB on all machines, maybe if you have 8 MB or not enough free capacity on your primary partition (drive c:) for a big swapfile, that could be a reason for strange "bugs" when dealing with such huge databases like Fritz' trees. Does your machine handle any kind of big database well? Maybe it breaks under the sheer size of the DB ... Don't laugh, my AMD K6 would crash *only* on chess programs, it didn't matter which one I tried, because only chess programs would stress it enough to reach a too hot temperature very soon ... The same problem with burning CD-ROMs: You only find out that something's wrong when the CD writer spits out another recordable CD with cryptic error messages ... > KK suggested, at first, that that was maybe because I am using Windows 3.11? >But the user that had it worse than my case in using Win95, so...

Sorry, but there's never a way to be 100% on the safe side with any piece of software beyond small programs that display "Hello world" on your screen ... Moritz
