Hi,
Please do not attach binaries, even if they are free.
Instead use downloadlink, I guess it`s https://github.com/wuyudi/inRm3D/releases/tag/2.869-200510 , right?
Could you tell us what wine-version you use, also because I cannot reproduce it.
I can click in the black area and several points (A,B,C..) are displayed.
So maybe upgrade your wine version?
