Ezra, Thanks for the tip to use www.tinypng.org . It took a bit of time but it turned my 121MB app files to 71.6MB app. 

When I launched IB3 tonight the program won't load right away and I get a variety of strange error messages….. such as "stack is corrupted, check for - backup file".  I click ok and the app will open.  I close the app and reopen it and it takes about 30 seconds to open IB3.  Also got this other odd looking error message about an update…. and another one from apple asking if I want to report what is happening with my computer….  Thought you should know.

Actions set on animated elements randomly vanish from the Action Set Manager after previewing behavior in Interact mode.  In Interact mode the element doesn't always work the second or third time you tap the element (I do have it set to replay the behavior).  The targeted hidden element Shows and animates once and then the animation loop stops working, or the targeted element won't Show anymore.

I have tried to reset the same action over and over again in Design mode and some of the actions vanish after I preview in Interact mode. Very frustrating.

To reproduce:

Place (3 or 4) animated (png sequences) on the stage. No actions are assigned to them.  Make them NOT visible in interact mode.  

Place (3 or 4) several static image elements control the animated png sequence with these chained actions:

On Tap > Show > Animated PNG element, Animate > Loop > Yes, Transition > set coordinates > Bounce Yes > Replay  Yes, Hide > Other animated element(s).
