Running Version 18.104.22.168 on a reasonably modern Win 10 machine.
Very recently, data entry into a newly created calc spreadsheet has become very laggy. It takes a couple of seconds for each a cell to open to accept data. Newly entered data takes a few more seconds to appear in the cell. Moving to a new cell leaves the old cell blank for some some seconds before data reappears. Calculations that should be instant take a couple of seconds once the instruction has been entered.
Problem does not exist if I am editing an older existing spreadsheet. Even with old and new spreadsheets open in separate windows I am able to work normally on the old sheet and not the new. Seems to rule out computer problems.
I have tried both upgrading to 5.3.2 and uninstalling and reverting to 5.2.7/ I have tried renaming the App Data user file and seen a new one created. But the problem is persistent. Can anyone help sort it out please?
Any thoughts or guidance please?
