This concerns the failure of Calc to export the current sheet as jpeg. I am using Version: 6.4.2.2, on a MacBook Pro under OS 10.15.4
Export as jpeg worked well on sheet of a multi-sheet spreadsheet. The problem is this: When I tried to save the last sheet of the spreadsheet, it insisted on exporting the previous sheet! How can I get Calc to export the current sheet as a jpeg?
