I'm very new to Vista. I got a compaq laptop two days ago. Its running Windows Vista 64 bit home premium. When I use Firefox it runs fine for about half an hour. Then, it will not load the next page or go back, although you will see the activity bar trying. I've figured out that even after you close the application it doesn't really close. So ,I tried to close the app from the task manager. Now it still says that Firefox is already running. I went into the processes and tried to stop it, it wouldn't respond. The only thing I can do is restart. But wait. Bonus. I can't restart properly. I have to hold the power button down and then when I start back up it says Windows wasnt shut down properly. If you try to select restart or shut down it won't respond because of course theres an app running that wont close. Help please ,anyone?????
