I don't think you fix it. Still no blocks after 24 hour of mining! Back to previous version, block after 2 hours.
I explicit tested the uploaded version again, at least on my system the bug is fixed, and it's mining valid blocks on testnet.
But it shouldn't bother you anyway, the new version only fixed the Windows stratum support. The mining speed is still the same.
Ok i see, but testnet is not the same as real mining, so your next versions can include this bug with solo.
