Ok, so it is a new browser window. If you can hit "refresh" would that work? If that doesn't work, you could try to download another browser like Fire Fox or Netscape. Try one of those browsers out and see if you have problems then. If you have no problems with another browser than we will know that the problem lies with IE.
About your other question, I'm not too sure what to do about that, sorry.
I'm sure there is someone esle that has a better understanding of your problem and will supply you with some help.
