Flatten problem on newest version

I am testing IntelliCAD 7.2.6363.0.P.VC9 x86 on windows 7 32bit.

This is the newest version of IntelliCAD as of Mar 21, 2014.
(IntelliCad is the first and only s/w installed on fresh install of windows 7 32 bit )

To make project 2d drawing on xy, yz, zx surface, i created some
shape (subtracting one box from another shape box) and copy it
to make 3 same entities.

please check following link for problematic images.
