When I tried the same code on excel 2013, but Windows 8 the application.screenupdating = false stopped working only on the Windows or workbooks activate functions.
I have tried the following currentflag = application.screenupdating and currentflag shows false.
I tried debug.print application.screenupdating and it showed true in the debugger.
To make sure that each change was not effected by the debugger. Screen Updating will always show True in the debug window.
Application object and replace them with invisibility lines: Notice that you want to put the Word. Visible = True line in an error-handler or in a spot where you know it will be run if something goes awry. (If you do get stuck with an invisible Word in the middle of a crash, you can launch the Task Manager and kill the WINWORD.
