Would like to delete my previous reply at 6:57 p.m. tonight.
As it often happens, I found the answer while re-reviewing previous posts. To view .notx, .jrnl or .topx files in Tooltip Tool NT, you need to use the menu option Modules(3) and select one of the three file types in order to view, edit, etc. I was just using the File Open command which did not show any of these files.
Hope this helps someone, as I spent hours today trying to find a program that would to this.
