Recently this has started happening. I have a model open, sheet metal, and I would like to insert pem nuts. I go through the steps in toolbox, but then get a message that says, "Self-Clinching Nut_PMM" is open in another window...would you like to use this file? If I say no, then the command ends, if I say yes, the the PEM configuration pane opens, I choose the size etc that I want, then go to place the part. As soon as I place the part, the model zooms extents, and the command ends.
What is going on with this?
