I noticed a while ago that the score estimator in cgoban (the desktop version - (V3)) seems to be greyed out. Is there any reason for this? Have other people noticed?

I know two reasons for SE being grayed out:
1) You're using the applet. The applet does(or did) not include SE due to its size. Wms said he might add it to the applet since the internet got faster.
2) You're playing a game. It's only available in offline, reviews, teaching)possibly only as teacher) etc. but not free, ranked, rengo etc.

Thanks for the reply li kao

So i am using the desktop client - like the java web start one - downloaded from here http://www.gokgs.com/download.jsp, and it used to work.

I am trying to use it on svg files downloaded from kgs. I'm guess that counts as review - right?

(Although if i'm honest i sometimes look at ones that are in progress in kgs - probably not so great morally - but I guess the cgoban editor wouldn't know)

3) You're on a board size different than 19x19.
4) The score estimator can't work out the score (not sure if it greys out in this one).

Forgot your 3). For 4) it's enabled but shows an error.

Mystery Solved!

Sorry about that - hadn't realised that it was only for 19x19. That also explains why it seemed sporadically to be working - I normally play 13x13 - since I haven't really got the hang of long term strategy, but every so often i did - and then I guess score estimate works.

Weird it only works for 19x19. I would have thought it would be roughly the same algorithm for every board size.
