I typed a long SMath Studio file using the latest stable version. After saving the file, and re-opening I get a red bar and missing half of my document. Is there any way to recover it? It has happened to me at least three times since I loaded the last version of SMath Studio. I had produced PDF files from my other files, so I didn't worry much. But this one I spent a long time typing and didn't printed it to PDF before closing it. HELP!
As I opened the work sheet, the scroll bar didn't report red dot, only a red | in the empty text box. True: past | empty. An interesting document as I did some work on "nanofiltration NF 200"
