I have two text/html modules side by side in two separate panels.    I have my original page that I created a list inside the text module.

Here is the link to the page that looks like it should............

I copied the page referenced above and made the "list" module "referenced" when copying so that it changes in all pages when changes are made.
here is the link to the second or "copied" page and you can see the module on the right has gotten wider and the left side smaller.
this is not consistant as we have done this same thing with about 100 pages and it happens 1 out of 10 times.

Can you help?   My phone is 866-521-3595 ext 1  if you have any tips.

Yes - they are all of the same skin.  I have not used that tool - do you have a url to refer me to for more info?  Thanks!

thank you very much.  I forget to look at the source code sometimes.  It pointed out to me that there were <br> in the paragraphs that created the returns.  Thanks! I think we figured it out................
