You may or may not be experiencing Technical Difficulties

I may be experiencing technical difficulties on your screen. I apologize. I recently discovered (thanks Jonathan) that my light purple background was dark purple on some screens (his, at least.) I've changed to white. But also some of my punctuation is coming out as garbled code (that explains a comment I read a week ago about this dude [me] needing to learn punctuation code.) That I'm looking into. But if anyone has had similar problems with Blogger, please drop me a line or comment. Thanks.
