Just had a client who requested that the playbar component in Presenter be eliminated.  Interestingly enough, they felt that since the content they were working with didn't contain any audio at all, it was futile to include the scrubber EVEN THOUGH there was animated elements on many slides AND they still wanted the attachments button, Back/Next and Play/Pause controls to remain intact.
 
Okay...no big deal....I don't necessarily agree...but no big deal.
 
Most of us would would have normally taken the following approach: publish your content, then dive into the vconfig.xml file and set the playbar value to "false".  Problem: it wipes out EVERYTHING!
 
Solution: A flash file that does the heavy lifting for us.
 
Here's how:
 
In order to kill the playbar scrubber while leaving the attachments and audio controls intact, use the following code on a single frame of an fla:
 
this.onEnterFrame = function () {
_root.m_controlBar.m_scrubBar._visible= 0;
}
 
Save and publish the flash file (I called it killScrubBar.fla) and add the swf to teh FIRST slide in your PPT deck.  Publish the PowerPoint deck and the scrubber/playback will be gone!
 
NOTE: Because Presenter 7 is set up for Flash Player 8, its best to code everything using ActionScript 2.0 as the coding environment.
