Thanks for your replies
I have a co-worker who came to me asking how to do it. She swore she accidently did it one day but did not write HOW that she had inadvertantly moved the tabs to be shown on the left rather than the default found at the bottom. I had never heard of it, nor did my boss - so I thought who better to ask than the experts here at MrExcel.com. If someone does find it possible, please post a message here.
We do not want to remove the tabs, merely move them to be viewed at the left or perhaps even across the top. Thank you !
