I’m getting a wierd error while attempting to debug my project:  
“You cannot debug this SWF because it does not contain ActionScript”

When trying to run a project where one of the as3 files contain a huge amount of data.  
Huge amounts = 1200 charactors a line and about 3000 lines of it.

I suspect that the error is related to the amount of data on that single actionscript file since after deleting most of the data, the project works.

I really don’t know what to do… Does as3 files have a limited amount of chars??
