That reminds me of another strange thing that happened – when I was saving……a message popped up to say something-er-other about the format and losing something-er-other if i saved it……..
So that’s what happened – I followed the advice windows gave me and saved it in the wrong format.
That is good to know! I haven’t been hacked, I’m just ignorant about some things. 
You learn something new every day – especially in this business.
Thanks, Wufu.
