Heehee. I hope you figure out what's going on with your computer. I've had issues with my Mac, it had to have the logic board replaced after it stopped registering when an ethernet cable was plugged in. I wish you tons of luck!
As for the chat, well.. yeah, I feel your pain. I just started typing away in the "quick reply" box, and copied and pasted the whole thing over to the next page... then added on to my responses to various people as I came across their multiple posts that I hadn't yet read.
Good luck with that, too, hee!
