Same problem on Windows XP with the same 20091102 build.

Hmm, all the equity values are actually a little different on Windows XP, but my setup is probably different on the two machines and the bearoff databases are different sizes.

The average seems to be correct with MWC values

Yes, of course. Here are a couple of examples:

-- average smaller than all values
Position ID: 4HPhASiwZ/ABMA
Match ID: cAluASAAAAAA

-- average larger than all values
Position ID: tpngAQrDzZEBIQ
Match ID: MAFvASAACAAA

and I have attached the screenshots from these two positions.

Version GNU Backgammon 0.90-mingw 20091102
Operating System: Windows Vista

Hmm, the average is only wrong in some positions. When it is wrong it is either larger or smaller than all the equities.

I have attached a screenshot from a position where it is wrong.

The Average equity in the dialog "Distribution of rolls" is wrong in the latest build 0.90-mingw 20091102.
