Sometimes, I cannot access certain websites, like Yahoo Answers, and my yahoo mail account...and sometimes other things. Sometimes if I reboot, it will fix itself, and one time I had to reboot twice. I am always able to access everything else. It is just one thing at a time. Sometimes it will come back on its own. This has been happening a lot, today. There are other strange things that it sometimes does, like restarting while I am no where near the computer, or freezing up. But, today it has just been this that I have been describing. When it is about to do this, it will always show an address at the bottom, and the address will have ulseek at the beginning of the address. Is this just a quirk of Vista, or is this something that I need to seriously worry about?
