@ Kevin - I'm using Mac OS X 10.7.5 with Excel version 14.3.0 and do not get a new blank workbook when I click on the Excel Dock icon. What version of Mac OS X are you using with update level of Excel?
@ Kevin and Jim Gordon - I understand now from Bob Jones's answer that this happens when I click on the dock icon
if i don't already have a document open. I have confirmed this with several programs. Maybe this is one difference between what you're observing and what Kevin's observing. Another difference might be that it only applies to
document creation programs, as it happens with TextEdit, Word, Excel, and Pages, but not with Graphic Converter, an image editing program, as is Photoshop.
At least I understand why this is happening now, although I don't understand why Apple should require this. Yes, a file must be open to do anything in Excel, but usually it's a file I've already been working on - I'm not such a whiz that I can whip out a complete
spreadsheet soup to nuts in one sitting. I don't understand Apple's reasoning - the reason I like the dock is because I can easily open programs, see what's open, and navigate between them. Yes, I can use command-tab, and do a lot. It's just been bewildering
why I keep getting new worksheets all the time and there's no way to turn it off.
I don't agree with Jim that it is harmless to have new blank documents automatically created when you don't want them. When i am working in Excel I am working in a mode that is difficult for me. It takes all my brain cells to keep in mind what I need to learn
and remember, in order to accomplish a particular goal. I don't use it all the time. I almost always have to come online to forums like this multiple times when working on any given spreadsheet. If it weren't for people like you volunteering your time to explain
how to do things in clear English, I wouldn't be able to use Excel at all - the built-in help instructions are not in a language that I speak.
So for me, any distraction from my train of thought and focus is harmful. It's like driving along and somebody throws a bucket of water on your windshield every once in a while. The water isn't going to harm your car or get you wet, but it startles you and
distracts you. This triggers stress reactions, which interfere with higher level cognitive functions. Seriously.
If you know it is always going to happen when you go under an overpass if you drive in the right lane, but not in the left lane, you can prepare for it and choose to go in the left lane. Of course, you would rather you didn't have to do that, but at least it
is predictable. That is how I feel about what I have learned here today - now that I understand it, I can manage it - but I still don't like it. But thank you all for your helpful explanation.
