I did more testing.  Finally it turned out the problem occurred in IE 7.  
 Firefox doesn't screw up the acronyms.  Even though abbr and acronym both
are defined as allowed tags in TSConfig in the page properties, I had to
add the following two lines in the site's template setup to prevent IE
from screwing up acronyms.

lib.parseFunc.allowTags = table, tbody, tr, th, td, h1, h2, h3, h4, h5,
h6, div, p, br, span, ul, ol, li, pre, blockquote, strong, em, b, i, u,
sub, sup, strike, a, link, img, nobr, hr, center, font, tt, q, cite, abbr,
acronym

lib.parseFunc_RTE.allowTags = table, tbody, tr, th, td, h1, h2, h3, h4,
h5, h6, div, p, br, span, ul, ol, li, pre, blockquote, strong, em, b, i,
u, sub, sup, strike, a, link, img, nobr, hr, center, font, tt, q, cite,
abbr, acronym

Anybody know why?

Thanks,
