I complained in a recent posting about very very slow refresh times for Excel
2007 charts, especially for charts whose axis were not default ranges or for
worksheets with large data sets. I am pleased to say that the hotfix posted
at http://support.microsoft.com/kb/938538 has provided an incredible increase
in speed. There is now almost no perceptible chart redraw or refresh time,
even in a very large data set with more than 70K rows. Wow!
