I entered data on an Acrobat Form using Preview (Snow Leopard) at home. When I opened the file at work using Adobe Acrobat Pro V9 on a windows computer, the fields appeared blank. However, when I clicked in a field, the data were there, but became invisible once again when I clicked on another field. The data also would not show up when printing a hard copy. I then went to a Mac and double clicked on the file, it opened up in the default app which was Adobe Acrobat reader, same thing happened, meaning that it wasn't a windows issue. I then opened the file up on this other mac under preview and was able to see and print out all the data. Anyone have an idea how I can keep the data visible or would I have to use acrobat pro rather than preview to enter the data so that other people who don't have preview can see the information?
