Computer Problems

One software issue that constantly frustrates me and I have constantly tried to override and outsmart is the autoformating in Microsoft Word. I will be typing along and getting my information down and suddenly the program starts putting 1.5 spacing between lines. Did I ask for this? No. Did I want this? No. I was perfectly happy with single spacing. Then I will be making spelling lists for my students to use for their homework. I am copying and pasting into a table because I don't want to use a whole page for 20 spelling words. However, when I paste the words the last one constantly drops the number AND the numbering is continiuous instead of starting over. I can go in and change that but it takes time. In short, I hate autoformatting, it does me no favors.
