So first of all, the positive feedback.
MDZ 9 is absolutely magnificent. Having an AMD graphics card as I do, I found earlier versions literally impossible to enjoy as the slightest change in the 2D pattern would take ages to accomplish.
Now the negative - MD's native avatars JUST WILL NOT LOAD.
The whole program just shuts down. Funnily enough though, when I updated to the very latest version, it did load a native avatar once. Just Once.
