Mirek I'm not having a go, in simply asking a question, the thread is about maya crashing, you posted about the insert edge loop tool slowing down your PC and leaving lots of verts about, and then when you delete the edge it leaves verts there....

Yes you were saying what happens with your PC, I was saying what happens with mine, and I said how you might get round not having to delete a lot of verts.

As for your first and second paragraphs, well thats quite a thing to say and judge people by.
