An "Undo" function is available in the CDXStreamerTM toolbar if the option to use it is enabled in Settings :
With "Undo" enabled, the state of your spreadsheet is stored before CDXStreamer makes any modifications to it. This includes any manual changes you make to your spreadsheet. Pressing "Undo" will restore CDXStreamerTM to that condition. "Undo" can be several levels deep. Once you "Undo", CDXStreamerTM also allows you to "Redo" or go forward in time if needed.
The "Undo" function is only available after a successful data retrieval. It is not available when CDXStreamerTM first starts, if another worksheet has been activated, or if you are working in another Excel workbook. Because of the time spent saving large workbooks, you may want to disable this function using the Settings button on the commandbar.
