FYI, I have had to apply the same fix for both 3.4.2 and 3.4.3 to get the checkbox to work.

After saying the work-around worked, I found that it worked in IE but not Firefox. I went back and tried moving the saveCell(iRow, iCol) into the handler for the button click event instead of ajax call where I was preparing the data to send back to the server (which was also called in the button click handler)

As a work-around I just parse and grab the value after substring “value=” in the cell. This in not elegant but it works for now.
