Going waaaaay back to the original question, yes, you can view the version 1.30 data logs with Excel but you need to convert them first. If you open CalCon and go to the Plotting tab, below the graph and above the "Dislplay", "Color" and "Export" buttons there is a text box. It may or may not have any text in it. Double click on the text box and it will bring up an open file dialog. Select the file that you want, then click on the export button. It will create a CSV file that is compatible with Excel. No, it's not intuitively obvioius and yes the 1.30 version has some issues. If it didn't have ACT available, I would use 1.20.
