Yesterday a quite annoying bug in the new ModelConverterX 1.8 stable release was reported that caused the selection mode to not work correctly after the model has been rotated. This bug had been introduced when the new interactive editing was added a while ago, but apparantly was not noticed in the development release. I have fix it now in the development release.

Since this bug has quite some impact on the selection mode and it was found very shortly after the stable release, I have decided to also make a hotfix for the stable release. So a new version of the stable release has also just been put online.
