Hs stopped working – OOReader Review

I have used this app for years and have found it to be efficient and reliable. However, it has begun to completely shut down when moving about half way through a document. It has never done this before so Pam not certain what is happening. The document I use the most with this app is only 10 pages long, so it’s not too large. Must be a big, but wish it could be solved!!!
