I am evaluating Aspose.Cells and have a question. I have built a sample application that fills out an excel sheet and launches it in a separate window. I have tried both 'OpenInExcel' and 'OpenInBrowser' options, and they both result in opening in a browser, though 'OpenInExcel' does give me the option to save before opening it.. But after it is open in the browser, I would like to do a 'save as' on the excel sheet. I tried clicking the disk icon in the toolbar, but nothing happens. Is this a restriction of the trial version?
