Next version is based on a totally rewritten code (99% python). So all bugs (crash, installation, etc),
will be automatically fixed, because next version is very simple to compile, and the opengl features are reduced to minimum in order to have a fully crashproof application even on very old machines and graphical cards.
The new GUI will be a revolution too.
Stay tuned, and excuse me if I don't follow personally the 0.9.1 code/installation problems.
Cheers,
Manuel
