TLA Systems has updated DragThing, the dock application for Mac OS X (10.2 or later), to version 5.1.1, which adds enhanced contextual menus, AppleScript support and speed improvements. It also offers a workaround for a reported problem with the recent McAfee Virex 7.5 beta that could cause DragThing not to quit properly on shutdown, restart or logout. This is a free upgrade for registered users of DragThing 5. Upgrades for registered users of DragThing 2 or 4 costs US$12; individual licenses are $29; and five and 10 packs are available for $99 and $149, respectively.
