> I havent been able to get the blender to work on two curves as I did previously.

For blend and loft, you need to pick nearby the ends that you want to line up. That's possibly one thing that you're running into.

Here's an illustration (using loft here):



When you click on the curves to loft or blend, MoI will match the endpoints that you clicked nearest to. If you happened to click near opposite ends, you can easily end up with twisted stuff.

If you do a window select around objects instead of clicking on them, MoI will do an automatic process to decide which way to align things. Most of the time the automatic process works well, so maybe I should revisit this and make the automatic process run even when you select by clicking as well.
