Using window eyes 5.5 with IE7

the results are similar to jaws and voiceover:
"it just reads the
superscripts and subscripts as seperated blocks with no particular
disctinction or announcement of how they differ."

I had a look at the various settings in JAWS/Window Eyes to see if I could
get them to announce the sub/superscript differently, to no avail.
