I'm surprised nobody has mentioned problems with FTP links, either in the release notes or this forum. I've been having consistent problems with them for the last several Sneaky Peeks.
When I try to click on an FTP link like this one:
ftp://sources.redhat.com/pub/docbook-tools/
I used to get a directory listing in OW 5.1. In OW 5.5, I instead see TextMate open up a new blank document.
Is anyone else seeing a similar problem?
