Every time I type 'of' and hit the space key, Writer automatically changes it to 'off'. It's driving me crazy. I don't know if I accidentally hit a button, or if the cat walked on the keyboard and pressed just the right combination of keys, but I can't fix it. I'm a teacher and type a lot of documents for my classes, and it takes a lot of time to go back and change all the 'offs' back to 'of'.
What can I do ? Thank you in advance for your help!
