I did have some Safari issues with iOS 8. . . especially in FreeRepublic. Those are not yet resolved to my satisfaction. Most went away with iOS 8.1. Occasionally, backspacing while i am editing a reply or a post causes Safari to freeze completely. . . and that happens only in FreeRepublic's editing mode. I cannot find out why. It does not even generate an error code. Strange. The only way to get out of the freeze is to wait long enough and sometimes it clears itself. If it doesn't I have to quit Safari and then reload. Sometimes my work i am editing is still there, sometimes it is gone PFFFT, and I have to start over. Strange. Other then that, no issues.
I have had the keyboard freeze up as well, but only a few times. Come to think of it, it might have been when I was backspacing.
