My computer had a personality melt down, which necessitated taking it to the computer doctor. Although I could open some sites, I couldn't keep the windows open. Internet explorer and every other browser I launched kept shutting down as soon as they'd open. Which made it impossible to sign into blogger, to access twitter, or to even get in my email. It's been beyond frustrating.
Just picked the computer up this evening and hooked everything up. So far, it looks like the problems been fixed. Fingers crossed it stays that way.
