I've had the same issue in Safari as well. It means extra cursor work when typing, which is what quicktags is supposed to eliminate right? Also... switching over to Firefox isn't something I want to do. I've had way too much frustration trying to integrate my bookmarks with Firefox. There are a few other things that bug me about the interface as well- that I don't need to go into here. I'll test with it, but I don't want to work in it. Frankly, I'm waiting for the bugs to get worked out in Flock and then maybe I'll switch over to that instead.
But has anyone else come up with a fix for this wierd little problem in Safari. I don't care so much about using quicktags, but it seems a few plugins use quicktags, which is why it made it necessary for me to hack the code so they'd be visible in Safari.
