Hello bonesawmcgraw,
Welcome to vista Forums!!!
I am not sure i understand your problem. Are you having trouble connecting to JUST youtube, myspace, and yahoo? There may be a problem with you internet. Are you using a wireless router to connect or are you hardwired to your modem? And i am not sure what pop-up you are talking about. Can you tell me what it said or what you had to do to make it come up?
Hope to hear from you soon,
Ben
