Thanks to everyone for your replies. I haven't used SMART board or Qwizdom much, but your responses have made some things more clear to me about how to use them. I quite clearly need to look into both SMART board and Qwizdom quite a bit more. Based upon what I had seen I assumed they integrated quite straightforwardly, but obviously not.
For the record, the only reason that I have Qwizdom as the brand of voting machines is because these are the ones I can borrow from university for free. Are there any other brands you'd recommend for voting machines? As a resource I think I'd find them useful, but obviously that would have to be at the right price AND right difficulty in terms of setting up.
Also, I haven't found any problem with having to set Administrator rights for the software either. I've got Windows 7 and version 2.042 for reference.
