    Wow! I did not expect an update after so much time.
    Thank you very much. I hope that the performance with multi-core is solved.

    How strange, when I try to open this version of MMD, my laptop is not letting me, because it deems it as dangerous.
    However, is has never done this with past versions. I use Windows 8.

      It’s highly unlikely that this new version is any more dangerous than previous ones (as long as you downloaded it from here or directly from Higuchi Yuu’s homepage). More like a “false positive” in your antivirus software. Still, if it makes you feel more safe, just keep using the old version. As mentioned above, it’s just a small bugfix for something that might not even be present in Windows 8 in the first place.

    “Windows 10 Fall Creators Update (ver. 1709) If there is a sense of incompatibility with the motion on the updated PC, it seems that there are many parts to stabilize by applying the update program “KB 4051963” ”

    November 30, 2017KB4051963 (OS Build 16299.98)
    “…Addressed a performance regression when users run full-screen Microsoft DirectX 9 games and applications.”

    Current version (2017/12/3 20: 00 JST) version is Ver.9.29 (2017/12/3) Windows 10 Fall Creators Update Point 3 where the mouse moves incorrectly when applied Update is fixed. Please confirm that corrections have been added

    “Update of MMD (2017/12/5 10: 30 JST) Ver.9.30 (2017/12/5) Windows 10 Fall Creators Update Points where the mouse moves wrong when applied 4 Update Fix is ​​added and fixed. please confirm.”

    Apparently the new “flurry” of releases is nothimg more than a hotfix for a particular problem that appeared with a recent Windows 10 patch. No new functions are to be expected
