Snowmint Creative today announced the release of Ultimate Pen 1.4.3, a software-only solution which creates a full screen, transparent window, allowing you to draw on top of any application. While it can be used for drawing on anything, it is particularly useful when working with presentation software. You may add notes, make comments, or add illustrations directly on the screen. Changes in version 1.4.3 include: revised help pages for improved clarity and better navigation; updated to Universal Binary version of eSellerate framework; clipboard support; System-wide Hot Key; bug fixes; and more. Ultimate Pen is priced at US$19.95 and requires Mac OS X 10.2 or later.
