Publishing the .muse file on a test site creates the page looking good, however while opened in Muse if I navigate to the edit the Website-PORTFOLIO and select the heading and the content of one of the right panels there's a difference of 1px's between the two, please have a look here: http://screencasteu.worldsecuresystems.com/Cristi/2012-05-21_1547.swf
So, please modify the page and align all elements using same coordinates and then try again, and if there's still a difference between the two pieces increase the size with 1px: http://screencasteu.worldsecuresystems.com/Cristi/2012-05-21_1552.png
Let me know if this helps.
Try to group the elements like text and everything related (i.e. bullets) and publish the site again.
Have a look at the published site: http://aad6a8dasda7das9d.businesscatalyst.com/Website-PORTFOLIO.html
