Thanks for your response....
I followed your steps above (without the click button Left Justify - not relevant for this) and I have checked it out on two other computers in addition to my own... and it definitely happens for me.
Have you tried changing the font colour throughout the email? I don't have problems changing the font colour of the first sentence - "Check out our latest Newsletter and some of the great events happening at this summer!", nor the titles themselves. But as soon as I try changing the font colour of "Lorem ipsum dolor" of under the Item 1 Title or 2 or 3, the problems start.
I am using IE 8 version 8.0.76 in case that helps...
Thanks for your help!
