Trouble with select/copy/paste

While attempting to select and copy information from either a book or a website, using a Focus 40, my student and I are running into very inconsistent results. Here is what is happening:
• Sometimes while selecting words/sentences the content is also highlighted on the screen and sometimes is not (this is important as the student is a dual media learner and relies on a combination of braille and print)
• Sometimes what has been selected (either if it is highlighted on the screen or not) and then copied using c-chord, it copies and sometimes it does not.
• Sometimes VO will randomly speak something as “selected” when in fact something else has clearly been selected.

Any feedback/suggestions appreciated.
