I put up a new patch for this Aug-1 build here: http://moi3d.com/beta/Aug1_patch2.zip

This fixes a few meshing bugs and a few other assorted bugs.

To install the patch, unzip to get moi_lib.dll and just copy that over top of the old version in the Aug-1 version in \Program files.

EDIT: One other file also needs to be patched, copy the Sweep.js attached here over top of the old version in the \Commands sub-folder to make Sweep options work.
