In a nutshell:
New computer running XP Professional, I was using W2K to export data
from Oracle, and into Excel.
The previous options to get it into Excel was to click on either
"Open", or "Save" from the dialogue box. I'd select "Open", and a
resultant list of apps would allow me to select Excel as the place to
export to, and would subsequently populate a new Excel sheet with the
exported data. Nice.

Now. . .with XP, the options presented do not include the option to
"Open", (only "Save" or "Cancel" appear). I can save and then navigate
my way to the file, and open with Excel, and map out all the fields,
but it was alot easier before.

I do use Excel exclusively as the destination for Oracle exports.
There is no file extension that I might re-associate to Excel.

Ideas on how to get back the ability to select an application?
