This just started today, I think. I routinely copy and paste fairly large spreadsheet data files from one spreadsheet to another. The current data file is 4 columns and 4000 rows. Usually I can do that in maybe 20 seconds.
Now I find I can’t paste it all at once, I have to tediously paste it in segments possibly a quarter as large or less. Not much rhyme or reason to it, it will let me past 2000 rows and the next segment won’t work unless its half that.
I’ve found I can’t paste a big slug of data like that from a LibreOffice sheet to a Gnumeric sheet either, though again, in small chunks it works. So I don’t think it’s a spreadsheet problem, something to do with the clipboard function in the XFCE environment?
