movie maker seems different when I last used it in May

The main screen that I always worked from, to add captions to, is very small.  I cannot see the text clearly, to see if there are errors.  I am referrring to the screen to the left of where the "movie" clips actually are, the screen where you add your title. Can anyone help me?  I make little movies for my friends and the captions are necessary, but I cannot see th microscoptic  text
