I just installed Excel 2007 in a computer with a 1.73 Gigahertz processor and
2 gb of ram. I have had two major problems. First, Excel seems to send the
processor into wait mode (hourglass) frequently and for extended periods.
Second, while working on a small spreadsheet, my chart and the cells that
depend on it go black when I select the chart. Then the menu area goes
patchy, failing to show any useful items. This despite the fact that my cpu
usage is only around 10%. All my other programs are working fine.
