I went back and did a complete re-install.
The first time: there were a few things missed.
The second time: no glitches at all; not even Iterator
ps: The machine is a modern asus core i5. I had also tried installing the live dvd (ubuntu 10.04). Although this is how I started, working well on an older dual-core, it did not have driver support for the laptop (no internet). It was throwing me back into time [ windows wrappers for (ndis??) for my hardware drivers - etc]
There will certainly be a place for the newer ubuntu 12.04 live DVD version when it comes out.
