I had a worksheet with 300 rows of data, and 8 columns. Moving from cell to cell took 5 secons or longer. I copied the values pasting special to a blank workbook. Same thing happened.
On the new workook, with only the one tab of data, I deleted all rows, and all columns, leaving what should be a blank worksheet/tab. Same problem, the curor movement was slow. I type a number and hit enter and it takes 5 seconds. The other two tabs are blank also, but I can move the cursor around and entering data on those sheets flys with great speed. I never copied data at all to those two tabs. However, on the first tab where I originally had data, I get hung up even moving one cell with the cursor key. There must be something hidden. I saved the worksheet and the size is 649KB. I called up a new blank workbook saved it, and is only 8K in size. There has to be something hidden behind the scenes. I have no hidden rows or columns, and I deleted all the rows and columns and have the same problem. Someone please help. I need to use my 300 rows of data and can't filter or move around without gettin hung up.
