Subject: new IE bug (confirmed on ALL windows)

It is definitely a margin/padding problem. For example the following
code will crash it:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3c.org/TR/1999/REC-html401-19991224/loose.dtd">
<STYLE>
.supp IMG {
VERTICAL-ALIGN: middle
}
</STYLE>
<P><A <It>.</P>
<DIV class="supp"> <A><IMG>

While this wont:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3c.org/TR/1999/REC-html401-19991224/loose.dtd">
<STYLE>
.supp IMG {
VERTICAL-ALIGN: middle
}
</STYLE>
<P><A <It>.</P>
<DIV class="supp"><A><IMG>

It seams that the space makes a difference.
