Have you ever bookmarked the last viewed page in a book to resume the
reading effortlessly next time? I guess most people usually do that.
Likewise, you may want to do the same thing when viewing a PowerPoint
presentation, especially the one with numerous slides. Certainly,
it's better if the presentation will memorize that by itself.

Without question, such "memory" will do a great help for PowerPoint
users. Especially to those who should present numerous slides to
others. If the presenting is interrupted for some failure, you should
resume from the last presented slide, but spending time finding the
right slide will bring negative effect to your viewer. Also,
such "memory" would be a good assistance for teachers in class. Then,
how to let PowerPoint "memorize" the last viewed slide?

Please do the following steps:

1. Download and install PPT2Flash (http://www.sameshow.com/powerpoint-
to-flash-pro.html#110)on your computer.

2. Click PPT2Flash Professional ->Setting.

3. In the Setting dialog window, please click Playback and then
tick "Start from the place where I left off last time".

4. Click Publish. This will transfer your PowerPoint to Flash movie
which possess Memory function.

To my part, PPT2Flash is a good Flash authoring tool for educators,
businessman, and trainers. If you only want to convert your
PowerPoint to Flash other than some other advanced functions (such as
memorize, orientation, synchronize video and presentation, slide
branching, comply with SCORM and so on), I suggest you choose
PPT2Flash Standard (http://www.sameshow.com/powerpoint-to-
flash.html#110), PowerFlashPoint
((http://www.digitalofficepro.com/powerpoint/Power-flash-point-
converter.html)), FlashPoint, Pointcast(http://www.pointcast.com/)
and other tools.

Really hope this tip can help the one really need.

Best wishes
