New Problem

Today I discovered what I think is a new problem.

I've been using the work around for the locked files and that seems to be working most, but not all the time. However, this morning I was working on Ehicon, Inc Documents #2 to #90 and while I'm transcribing the OCR copy disappears. I have to click my mouse on the blank side of the screen to get it to come back. This has happened in 5 files I tried to work in.
