Frustration

I spent a lot of time preparing the next post for my Four-Color series. It contained a 21 line table with headings all carefully lined up with spaces. It was saved and I left it for a while. When I returned to edit the draft, all multiple spaces had been replaced by single spaces including the double spaces that I was taught in typing class (1943?) to put at the ends of sentences. aaagh! I suppose I can use Photoshop Element's typing tool to recreate the table as a picture. Does someone know a better way?
