I prefer to open different subjects in different windows. And since I'm usually not doing too much on the computer, email, weather, looking something up, I don't think I'm taxing anything.
One thing I might add about this problem is that The Weather Channel web page, the page that seems to give me the most trouble, seems to do a lot of resizing or something. It changes quite a bit as it's loading.
I was just now opening and closing the weather channel page. It opens with the banners at the top filling across the screen, and the weather info below a little sort of filling the screen. Suddenly the lettering in the banners gets a little bigger and the weather info fills the screen from left to right.
I really don't know if that has anything to do with the problem. It's just that that page does the most resizing and gives me the most trouble.
I better also add here that while opening and closing The Weather Channel several times to check the resizing thing, I was NOT sent back to the previous page. Most days, I check The Weather Channel 2, 3, 4 times a day without restarting my computer, and am sent back to the previous page.
