My site is: http://www.personal-authenticity-project.com
I've developed the site in Firefox. Yes, much of the site was developed ignorant of the problem with pasting from MS Word to WP editor.
The problem is that in Firefox, the post displays appropriately across the length of the defined post body width. On IE, it displays as a very small column of text.
BUT... when trying to correct it: nothing corrects. AND, when testing by originating a brand new post with no pasting, just entering any text and previewing, the same problem.
I've tried to correct the MS Word paste posts by: 1) copying to textpad; 2) saving textpad; 3) reopening the saved file; and copying; 4) pasting the text to a NEW test post name, and 5) previewing test posts... AND same problem.
