This is really got me stumped. Two years ago I was pretty confident in MX2004 but have been away since 2006. Now I have CS3 and have ‘lost it.’
I have a button with a gotoAndPlay behavior on it and it just won’t work.
I even cut and pasted from another doc that I made that does work but then it gets in this one and it doesn’t work.
Attached is the file. My pride hopes it’s a bug
