There is a patch for Opera 9.5 out today:

The patch constists mostly of security and performance fixes, though I don't think that the annoying, but bearable "addresses don't move to the top of the list when clicked upon" "feature" was fixed. Oh well...
C. P. U. Its not a big processor... Its a series of pipes!
