My use case is: I am running Chrome and filling in a web form. For one text box that I need to fill, I need to get the data from a spreadsheet. So I open the spreadsheet using LibreOffice Calc, copy the data, then close it and try to paste into the web form. Unfortunately, at that point, I find out that closing Calc has caused the clipboard to be cleared. Other applications don't do that. Is there a way to tell LibreOffice not to clear the clipboard when I exit the application?
(I know a simple workaround is to not exit Calc, but I am in the habit of closing applications as soon as I no longer need them, and this is what I do when I paste from other applications.)
