Please provide more information. Your operating system, version of LO, file format, and the exact nature of the problem you are experiencing. LO Writer does work and it works quite well, so it could be you have either found a bug or come across a particular situation where greater clarity is required. Either way we need to know more about your problem. A sample document would also help.
