The imported data is not always up to date with the source pages when I load the spreadsheet. When this happens, F5 refresh does not help. Nor does Ctl-F5. Apparently there is some kind of caching going on.I'm thinking that they may be limiting the URL fetches when I try to refresh too often - like when I'm actively modifying my spreadsheet.Doc reference: http://docs.google.com/support/bin/answer.py?answer=75507
What are the refresh characteristics of the Google Spreadsheet Import functions?
