So Hal pointed out that mozCC 1.1.4 (the latest release) doesn’t work right on Windows XP. Unfortunately he’s right. Well, sort of. When I installed it with Firefox 1.5 on Windows XP Professional, the (CC) icon shows up in the status bar, but none of the license attribute icons (by, share-alike, etc) show up. It appears that this is actually a line-endings problem: the icon graphic files are flagged as ASCII in CVS, and were apparently borked when I checked them out of CVS to do the build on Windows.
So this of course demands an updated build, but I’m choosing to hold off for just a little while. See, I’ve been promising a new and improved mozCC for months. And whlie I know I won’t have time to really do much in the near future, I would like to do a few updates. See the upcoming features page in the Yiki (what’s a yiki?) for details.
