Quote - I do apologise if I offended you in any way with  my semi-curt response to your most generous suggestion. Maybe the colour I used in my response gave the impression of anger, sorry 'bout that.

It is my fault. I am in a horrible phase of my life and I overreact to everything...

BTW, I read that also UVMapper is able to perform the cleaning job. A well known cause of trouble among applications are silent limits on the number of vertices per face: the OBJ format theoretically can handle un unlimited amount of vertices per face, but actual applications can create troubles starting from 5 (and sometime less) vertices...
