In the edit weldment interface, on a rare occasion, when I switch between "groups" of weldment, and click "locate profile," and not move the "camera" at all, I can then select a point and click on the "alignment" box and it works.

However, this does not always work. And I cannot figure out why I essentially can't select points.

I have tried the "filter vertices" option and it does nothing,

And it also will allow me to select lines, even with the filter vertices option. This is confusing.

I read something about video drivers being an issue, so I updated them but nothing changed.

I have a Lenovo W530 with a K2000 video card
