Attention all Vista and Windows 7 users:

Over the past many months, we here at Holophase headquarters have been working on a new version of the program, re-writing it at the deepest levels of the code while leaving the visible high-level features intact. The new version (OmniGlyph Version 6) is now available for download. It's internal drawing engine has been completely replaced with a new one designed to specifically match the new display paradigm presented by Windows Version 6 (Vista, Win-7, and Win-8). The user interface is identical to OmniGlyph Version 5.5g.
