I have a multi-sheet workbook. The first sheet is a summary of results from the rest of the workbook. I would like this summary sheet to auto-refresh itself each time the sheet is activated. The VBA code triggered by the Worksheet/Activate event feeds some parameters out to other sheets, then copies back the results to the summary sheet of the workbook. While doing so, it keeps "reactivating" the first sheet, causing it to get into an endless loop that is triggered by the Worksheet/Activate event. Any ideas re how to avoid this? Essentially, I'd like the Worksheet/Activate event to go dormant for 15 seconds or so each time it is triggered.
