Option-Click in Scroll Bars for Jump Scrolling

In Mac OS X in general, and thus in most native Mac OS X applications, hold down the Option key and click anywhere in a window's scroll bar to jump to that spot (rather than scrolling one screen). If you like this behavior, you can make it the default in the Appearance preference pane. For "Click in the scroll bar to:" select "Jump to here."


QuickTime 7.1.5 Patches Panther, Tiger, XP, Vista Exploits

Send Article to a Friend

Apple has released an update to QuickTime for Mac OS X 10.3.9 and later, Windows XP, and Windows Vista. QuickTime 7.1.5 fixes numerous bugs, along with a flaw that could enable a maliciously crafted file to crash a program employing QuickTime or to allow arbitrary code execution - a phrase that often means there's a potential for an attacker to gain control of a computer or, at least, install malware.

Affected file types are broad: 3GP videos, MIDI files, native QuickTime movies, images in the venerable PICT file format, and QTIF files. Apple's notes indicate that a user need only open a maliciously crafted file, which means that Web sites could be used to launch attacks by embedding QuickTime documents in the right format.

There have been no reports of this flaw being exploited in the wild. A previous QuickTime flaw related to handling of JavaScript was exploited, notably on MySpace. Apple claims to have provided a temporary fix to MySpace, but it's unclear if that fix has made it into QuickTime 7.1.5.
