The latest nightly build of Mozilla (the new Netscape web browser) fixes the scroll arrow problem I’ve been having in Mac OS X–you could click on the scroll bar arrow and it highlighted, but no scrolling would occur. Now it works. Checking Bugzilla shows that the bug was resolved on Friday (the patched was commented “Shot in the dark, but seems to make sense 🙂 ” ).
Also, in the preferences, you can set Mozilla to always open the Download Manager when downloading files. I’m not sure when that became available.
Looks like Mozilla 1.2 on Mac OS X is ready for beta status. My Windows XP build seems pretty stable too.
