Bob:
On a Mac using the latest OS (10.8.5)
Firefox works fine to load and write files; there seems to be no choice where
they get downloaded, though I can control that in the browser preferences. I
note that the name of the file selected to load is given in the dialog.
In Safari there are a couple of issues. The name is not given when the file
is chosen. More importantly, we are back to the lines issue. I have cleared
the browser cache, and, in fact, disabled it. Perhaps Otis can confirm that
glitch??
