MacOS 10x IE 5.1/5.2 will crash if it encounters in an external style the following combination
vertical-align: (any value);
background: inherit;
If these styles are applied inline, the crash will not occur. This is a bug in Internet Explorer 5.1.x 5.2.1 specifically on MacOS 10.1.x and 10.2 platform.
The presentation of styles in an external stylesheet is fully standards compliant.
Examples of the bug are here:

IE no crash --------> source

I can confirm that the page crashes IE 5.2.1 on OSX v10.2.
I downloaded the html and CSS file, and narrowed the fault down to the CSS
file by removing the style tag. Every time I loaded the page with the CSS
included, IE crashed. Every time I loaded the page sans-CSS, it did not.
Then I went through the CSS file to see what I could find. Through a process
of elimination, I narrowed the bad style down to this one:
#headHelp {
width: 350px;
text-align: left;
height: 72px;
vertical-align: top;
background: inherit;
}
Then I started removing individual styles and found that by removing
"background: inherit;" (the first one I tried, actually) the page
stops
crashing IE. It can't just be "background: inherit;" however, as
this style
appears elsewhere in the sheet and I got IE to stop crashing by removing
just the one incident.
Through a process of elimination I determined that it is the combination
of
"vertical-align" (any property) and "background: inherit;".
I also
determined that this crash does not occur if the same styles are applied
inline. I have posted an extremely simplified test case here:
<http://www.ianleckie.com/ie_crash.html> (styles in head)
<http://www.ianleckie.com/ie_doesnt_crash.html> (same styles inline)
Very strange. If someone could verify my conclusions, I would like to know
how to go about notifying Microsoft about this problem...
