My Excel 2016 is giving me the 'circular reference' warning after about every 3rd, or 4th cell, no matter if it is text or number. I even tried it on a fresh spreadsheet with absolutely no formulas. This started a couple weeks ago, as an occasional thing, but now it happens steadily, no matter which (of several) spreadsheet I am using. It happens whether I am entering down a column, or across a row - numbers or text.
It takes 3-5 seconds for each number to 'register' and move to the next cell.
I use spreadsheets all day long and this is slowing my data entry to a near-stop, because I have to wait after keying each cell, then kill the message box each time it pops up.
I have tried shutting down, and re-starting my computer, and that makes no difference.
I have also tried 'error checking' in the formulas tab, going through every sheet of a spreadsheet set.
Help please!
