Hi Algoflex,
From the video I only see the hourglass icon you described but not any windows. So I have to ask you that the selection range was A1:F27, and after you clicked on "Ok" to close the "Select Specify Cells" window, Kutools selected Columns A, D and F?
BTW, could you advice what version of computer system, Excel, and Kutools are you using? Did you try to uninstall and reinstall Kutools with antivirus disabled?
