Source code jumps around when re-opening page?

Question

Is the following a common problem with Dreamwver CS4 Source Code view?
In an effort to make the code read nice and neat, like everyone else I try to indent and nest my code. For example:
<div>
          <ul>
                    <li>one</li>
                    <li>one</li>
                    <li>one</li>
          </ul>
</div>
But, upon saving a file and then later reopening it, I notice that in places the file does not keep my intended spaced nested layout i.e. the code jumps around on a line and I lose my neat indent spacing. For example:
<div>
          <ul>
      <li>one</li>
                    <li>one</li>
                    <li>one</li>
             </ul>
</div>
I have tried to set my preferences > code format > tab size to 10 to produce a larger indent which has improved the problem a little but not fixed it.
Others must have experienced this frustrating problem.
Is there anything I can do to fix it, like set further preferences to give me complete control over the page?
Thanks in advance.

Oh can it? I will look into this thanks Ken.
With regards the CSS, I found out about it on Lynda.com training videos.
- Dreamweaver CS4 with CSS Essential Training > Chapter 13: Testing and Deploying CSS > Formatting code for deployment
The process is as follows:
On Dreamweaver CS4 click Edit > Preferences > Code Format > CSS (button)
On the CSS Source Format Options screen, de-select the "Each property on a seperate line" check box and click "OK" and then "OK".
Then on your CSS page, in the left side panel, click "Format Source Code" and the "Apply Source Formatting" selection.
The code will then condense for deployment.
You can reverse the process just as easily going backwards.
If anyone else has any ideas on code jumping around on a line please do let me know. Thanks.
