We just uploaded MeshCAM V8, Build 26 with the following changes:
- Changed the user interface to all native code, no elements rendered using OpenGL (for those with the “black boxes” problem).
- Added an option under Edit->Preferences to render thick or thin lines in the 3D view.
While the change list is short, this release includes a lot of new code so be sure and let us know if you find any new problems.
