The VBA macros work the same in Word 2003 as they do in later versions of Word. Except that from Word 2007 onwards, intensive text processing macros work up to eight times slower in the ribbon versions of Word than they do in Word 2003. Did you try out the doc/userform check (steps 1 to 8 above)? I suspect that the issue will be the same. It's a global issue, not one related to a particular macro.

Thanks to yourself & Aussiebear for your input. Often with these problems all that is needed is for someone to suggest an alternative way of looking at it to provide the stimulation to come up with a solution. Or to pose the question, What exactly are you trying to achieve (always a good question!)? That's what happened here. Great stuff, guys!
