FOR IMMEDIATE RELEASE

PreFab Software updates UI Actions, bringing "universal attachability" to
AppleScript, for Mac OS X 10.4 Tiger

NORTH ANDOVER, Massachusetts - April 29, 2005 -- PreFab Software, Inc. and
Bill Cheeseman today announced the release of version 1.1 of PreFab UI
Actions. UI Actions has many new features and an enhanced user interface,
and it now supports all of the new GUI Scripting and accessibility
enhancements introduced by Apple in Mac OS X 10.4 Tiger.

UI Actions implements "universal attachability" for AppleScript. With UI
Actions, you attach an AppleScript script to a native Mac OS X application.
From then on, the script will be triggered automatically every time the user
performs the actions you specify in the target application. A UI Action
script can respond to all manner of user actions, such as opening or closing
a window, selecting a menu item, editing a text field and many others.

PreFab UI Actions is universal. While Apple's Folder Actions and Digital Hub
Actions are specialized tools that let your scripts respond when the user
performs narrowly defined tasks, UI Actions goes much further. It allows any
accessible user interface element in any application to trigger a script in
response to any supported user action. UI Actions opens up whole new worlds
of possibilities.

UI Actions 1.1 requires Mac OS X 10.3 Panther or newer, but it works best
with Mac OS X 10.4 Tiger. It is a recommended upgrade for all customers.

Download a free, full-featured 30-day trial version of UI Actions 1.1 now at
http://www.prefab.com/uiactions/. This trial version will work even if you
tried an older version of UI Actions more than 30 days ago.

UI Actions 1.1 is a free upgrade for licensed users. The price for new users
is $35, with quantity discounts available.

scripts, releasing PreFab Player in 1994 with continued sales and support

X with PreFab UI Browser, a popular utility to support Apple's new GUI
Scripting technology. PreFab UI Actions, implementing "universal
