Following my initial foray into converting Jmol applets to JSmol/HTML5
for small teaching demos, I am now turning my attention to a research
web application for protein structure motivated (Motivated Proteins)
that has been employing the Jmol java applet for the last 10 years or
so (http://motif.gla.ac.uk/motif/index.html). I am happy to say that I
have managed to do a 95%-acceptable conversion and have mounted a
hard-coded mock-up at http://motif.gla.ac.uk/JSmolTest/. Thanks again
to Robert Hanson and the rest of the Jmol/JSmol team.

However...
...I have encountered what I regard as a bug in relation to the
rendering of text labels. In brief, the default label font for Mac
Safari seems imperceptibly different from bold, and is aesthetically
unpleasing, and, although this is not particularly important for me,
the default hover text is unacceptably ugly. The situation is similar
(albeit with some differentiation between plain and bold labels) for
Chrome and Firefox on the Mac (a year old iMac with a normal
resolution display running Mavericks). On viewing the mockup on a
student PC cluster running Windows 7, Chrome and Firefox look
marginally better than on the Mac, and only Internet Explorer shows a
proper plain label with an acceptable hover style of text.
This is different from the java applet version of the web application
running on Mac Safari (albeit running a very old version of Jmol)
where the text has always been fine, given that it is aliased.

Viewing the mock-up on my iPhone there is also no difference between
plain and bold, although the default is less bad, perhaps because the
phone has a Retina-display screen.

I have mounted a gallery of screenshots at
http://motif.gla.ac.uk/JSmolTest/text.html. One can also view the text
on my demo: click on the button for individual motifs and then on
Motif 1 - marked up as 12 plain - and Motif 2 - marked up as 12 bold.

I wonder if the font (if any) that is being specified is the problem.
Or is there some IE-only code somewhere?
