We´re facing a strange problem here. It does not really impact production but it´s something that certainly needs to be looked at.
I´m not going to explain it. It´s better if we go straight for "steps to reproduce":
Zimbra Release 7.1.3_GA_3346.RHEL5_64_20110928134520 RHEL5_64 FOSS edition, Patch 7.1.3_P1.
1. Compose a message in a new window
2. Select font Arial for example
3. Start typing and you´ll see that the font used is Times New Roman, not Arial.
This is Arial
This is Times New Roman
Same happens with other fonts. Bookman Old Style goes Comic Sans.
Happens both with Internet Explorer 9 and Chrome latest version. Firefox also shows the same behaviour but with less occurrences. So, that could be indirectly related to the browser.
Any help appreciated. I would like to hear if anyone else is able to reproduce this so that we can go ahead and fill in a bugzilla.
EDIT: Times New Roman is not even listed as a font option...
