Error while starting up Wings 3D

[micheus]

Just tried out the development release (strange it has the same version number, 1.5.2, as the stable release...), but the results are just the same.

Ok, thank you for check it.

I don't know what version you had used before, but maybe you would try to install 1.5.1 that is basically the 1.4.1 with lot of bug fixes. You can find all version in this link on SourceForge.net.
