I tried to export a form's entries in Windows 7, using Firefox 3.6.13. When I did, I saw this screen: http://grab.by/9eyu, which tells me that my .csv will be viewed using Notepad. Trying to open that document results in a jumbled mess; Notepad is not meant for csv files.
Viewing the document in the Firefox Download area, I see that it ends with .csv.txt. If I use Windows Explorer to view the downloaded document, it shows that it ends with .csv, but remember that Windows covers up the extension; that shouldn't be there at all. I am unable to (easily) open the document; it keeps trying to open with Notepad/Wordpad/Word etc.
However, there was no problem with Chrome 9.0.5, Safari 5, or Internet Explorer 8.
Thanks!
