Is the flash actionscript envirmoment buggy?

Hi guys.

I have been having serious problem with flash and that have me bashing my head up against the wall.

Currently I am creating a complicated animation via AS3 for a very high res flash file(1920 x 975). Initially it loads in data form a XML and then uses it to display content. Animation is driving by the use of multiple classes and is timed with listeners.

I have been careful to clean up all objects when not in use and test my work in flash and through HTML in a browser.

There have been multiple times were animation and data transfers have worked and then just stopped. I have toyed with these problems and they are inconsistent and do not make sense. Also viewing the flash file without changing anything produces varied results. It clearly does not make sense to me.

Note that viewing the same SWF through the flash player and within a browser gives different animation results. I have applied the current adobe updates and have the current flash player.

My 2 current issues are.

  1. I have a large map image that expands to fill the screen from a smaller image.
    5 tweens are places on it; x, y, height, width and alpha. At first sometimes it would animation correctly and other times not. Then it started animating half way. There is a ‘motionFinish’ listener attached which fires even if the animation has not animated to it correct final position.

  2. I have a movie clip containing dynamic text fields. I have linked this movieclips to an AS class that takes in an array and assigns the values to the fields. This works when it feels like it. I have tested the values passed just before signing to the text field and they are correct and exist. However the text fields get replace with blank text (these are populated with temp text to start with so I can seen what is happening). Even direct siging of text (IE this.text_feild.text = ‘Im not working’) will overwrite the text in the field with nothing (IE blank)

Both of these issues decide when they want to work and when not too.
It seems that animation are not completing there sequence. Often finishing half way.

I’m wondering if anyone has had similar issues?
Is flash a little buggy?
Is it because the animation is a high res?
am I missing something?
Can too much animation via AS cause issues?

It is really hindering progress and proving to be quite an issue.
