The map line "zings" (as I like to call them) are typically seen on machines
with ATI video cards (but there can be others).  The IDV has a preference
that you can toggle that should make the extra lines disappear:

Dashboard -> Edit -> Preferences -> System - Uncheck Enable geometry by 
reference

After making the change, exit and relaunch the IDV to make the change take
effect.

I have an additional comment:

- if your netbook is anything like my netbook, it will not make a good
  IDV demo platform.  The reason I say this is that the CPU is likely
  underpowered and you may not have enough memory to launch an IDV
  session that can do everything you may want to show case.

  Some questions about your 64-bit netbook:

  - what is the processor (and how many cores does it have)?

  - how much RAM does your machine have (and can it be expanded)?

  - how long does it take to launch the IDV?

Cheers,

Tom
