Slow OpenRoads Text Files

One of my sheets for a plan set is where we place all of our project notes, so the whole sheet is basically text. When trying to do anything in this file, it freezes up or acts ridiculously slow. For example when editing the text, I can type a sentence and then watch each character show up on screen at about one character a second. This makes editing the sentences and organizing the text very difficult. Another example is trying to move the text to align everything and it will freeze the whole file for every button I press. I copied these notes from a old V8i file so I am not sure if that is the issue or not.
