In View Source window, is there is long line (2100+ chars with no spaces) it doesn't wrap. If I scroll to the end of this line, some charactes at the end of it are placed one over another. Also, Home key If URL with example or screenshot is needed - I can send it.
dupe of bug 99457 ?
Mostly bug 99457, yes: the cruddy display of the unbroken line in various ways is other bugs, but they are also reported. *** This bug has been marked as a duplicate of 99457 ***
