Free Text fields in Receivables and Collections not updating properly

Users have found an issue in both our Receivables module and Advance Collections module that if they are entering text into a long form free text field it does not update properly. The example they provided was on the Comments field on the Receipt form in Receivables and the Notes field in Advanced Collections. If the user highlights the block of text it will update visually, but only in the highlighted portion.

I am not confident this is an Oracle specific issue, as I feel like I have seen something like this happen with Excel on occasion, that cells would not visibly update with scrolling unless you highlighted them.
