TLF text vs Classic text? Static text vs dynamic text? I've noticed things shift a little as well. Could also be font congruency issues or any number of things.
Yes I've found the problem!!! THE PROBLEM IS OPENING A CS4 .FLA FILE IN FLASH CS5
I looked around at many other things and the formatting was waaay off on so many things?! How in the world did that happen? Its as if i opened a microsoft word 2000 .doc in word 2010 and my fonts changed from verdana to WiNgDiNgS! Ok it wasn't that bad. But what WAS bad was that I spent so much time fixing those darn buttons and the animation, and then when I "tested" the movie, I saw all of the other formatting issues.
I uninstalled Flash CS5 and installed Flash CS4 and then opened the .fla file and guess what?
It worked perfectly and there were no formatting issues!
Be warned folks, using CS5 is amazing to create new content but watch out when "bringing in" your CS4 .fla work. Check everything carefully because the more complex your .fla file, the greater the chances of text, brackets, layer masks, graphic spacing, and animation will be either slightly shifted up/down/left/right, OR there will be huge gaps between pictures. Check your animated layer masks to make sure they are still covering/revealing what they should!
To tell you the truth, .fla files can be so complex, you're better off just editing your .fla file in the Flash version that it was created in. At least that way you won't have the doubt of "did i catch all the formatting errors?" looming over you during what should be your fun, unhindered creative process!
