Sorry about the delay with the new wallet - but IT IS READY!
There were several things wrong - I would find one problem and correct it - then test it for a week, and other issues would show up.
I do now know why the wallet has never staked properly since the day is was made.
It does now.  

Web site has been updated - you can download the new wallet at any time now.
It comes as a windows installer now  
github repo has been updated - please tell all the pools about the:

MANDATORY update.

The fork will happen at Monday Feb. 26 00:00:00 UTC
so there is plenty of time to spread the word.
