Create a Cylinder
Place mesh so that it intersects cylinder

Select Clyinder

   <Boolean>
       Operation: Difference
             Cylinder disappears and the intersection with meshed curve is left OR they both change color and can be moved independently
       Operation: Union
             Sometimes curved mesh makes a hole in the cylinder and sometimes it doesn't.
       Operation: Intersect
             Cylinder disappears but is still selectable

I had this same issue with 2.69, that's why I upgraded to 2.70.

I did not have this issue back in 2.66. Is that version of Blender still available?

You can get pretty much any version of blender here: http://download.blender.org/release/

Also could you check with a more recent version (or 2.71 rc1 if available for your platform) ?

Please attach here a .blend file with your problematic objects. 99% sure it’s either non-manifold (in which case boolean results are unpredictable), or has wrong normals…
