"New Worksheet" opens current worksheet and erases name
I am trying to start a new worksheet. Every time I hit "New Worksheet", one of my already created worksheets opens up, but the title is now "Untitled" and if I do "Discard and Quit", then my previously created file still shows the title "Untitled". That's a bit weird and makes this much harder to use. Am I doing something wrong, or is it a bug?
I'm using Sage 4.7 in Windows 7 through Virtual Box.
Update: The problem was in Firefox 5. But, I closed it and opened it again and it worked fine. And, IE9 worked fine. So, no idea!
