How to pin page in Illustrator CS5 so it doesn't move,scroll,stays in fixed position?

...unsure what you are needing here, as illustrator art board will always be scrollable inside the window by way of either the mouse (if you allow scrolling on your mouse) or by way of the window bars found on the edge of the document window...

...if you don't allow scrolling with your mouse then the only way the art board moves would be manually moving the window document bars or using the space bar short cut in illustrator to invoke the hand tool...

But it's annoying and unpractical and I believe there is an option , some thing like a lock -u press it and page inside of illustrator is blocked from moving.It's Illustrator after all...

...unfortunately no function in illustrator allows this, feel free to send Adobe a feature request they can add to the list of many other feature requests they deal with...

...it could end up being one of those features that might become annoying to have the art board locked in a workflow, because so often you need the freedom to zoom in on intricate small scale artwork...

...having to unlock the art board might well just become annoying to unlock when you forget it is locked in a workflow, a the moment you will have to just not move the art board, avoid zooming in and turn off the scrolling of your mouse...

At the very least you can position your artboard how you like and save a new view (View -> New View...) and then create an action that selects that view. Further, assign a key board shortcut or F-key to that action so when it does scroll you can at least fix it quickly.

One would have to wonder what it is you're doing with your scroll wheel that causes AI to scroll. It's only going to scroll if your mouse is hovering over the work area so it would seem, what ever it is your doing, do it somewhere else.

Hi V777, you are not alone, I have the same problem. I can't think what it is I am doing to cause it though.  Anoying isn't it?  

Why would we be seeking an Adobe solution to an Apple issue?
