Hello,

I have a project with 430+ as3 classes, which we have been developing for a year.

For about a month now, sometimes the FLA won’t compile, and no error or warning will be displayed. When I publish the movie, it takes about 60 seconds to compile, but when it’s finished, the swf file produced it’s only 1,1KB (instead of 850k which should normally be)  
and I get absolutely no Compiler Error or warning.

Sometimes, if I delete the ASO files and recompile, it works fine. Other times, this won’t do it and I would have to quit Flash and open the project again. I have “Compress movie” and “Reduce file size and increase performance” set to false for nearly 2 months now, because I read somewhere that Flash can have trouble with projects using hundreds of classes (this actually helped).

Last week however, I cannot get it to work. No matter what I do, it won’t compile. I try to delete a whole bunch of code from the Main class, get it to compile fine and then add a few lines each time, only to see that **any random line** of code can make it stop compiling again.

Any thoughts? Have I taken Flash to its limits? This thought is terrifying…

Thank you,  
Dimitrios
