RE: [Bug-gnubg] Beaver/redouble bug - erase analysis |

There's good news and there's bad news. The good news is that with the
latest 12/24 build, it no longer complains of my lack of doubling. The
bad news is that it now places 2 question marks on its own beaver as a
blunder. Now it seems to think (I'm guessing) in its analysis that it
didn't beaver, keeping the cube, but redoubled. That's the only
explanation I have for its own attribution of a blunder.
BTW, I had to go through a bit of work to do this since I found no way
to erase the previous analysis. This is a good idea for a function - as
some people may wish to re-analyze matches with future improved versions
for comparison. I also tried to export it to .mat to re-import, but it
couldn't read its own export file so I ended up having to edit it by
hand. I'll send you both so you can see BTW.

I fixed bug Dec 21 that could cause this kind of problems. Can you try
with a newer build, or send me (off list) the SGF file, please?
