Hahaha! You and me, sister, we're sticking it out here on TG Guide!
That's so weird, the problem with copy/paste. Seems to work fine for me, either with iPad or iMac. It's just ASCII text so it should be fine of course with anything. I'm glad you returned that laptop although I can't imagine what's going on with it.
Best of luck to you, finding a decent Windows machine these days. Cheap, yes, but Windows is no fun. :-)
