Error 1172

[mari8899]

I get this Error in Flash CS5 although I have NO AS 3.0 code in my Flash document, but when I export I get:

implicitImports, Line 1    1172: Definition __AS3__.vec:Vector could not be found.
implicitImports, Line 3    1172: Definition flash.desktop could not be found.
implicitImports, Line 17    1172: Definition flash.text.engine could not be found.

only and only code I have is stop and that was written in AS 2.0

Output says:

WARNING: Actions on button or MovieClip instances are not supported in ActionScript 3.0. All scripts on object instances will be ignored.

Check the actionscript version selected in your Publish Settings.
