I've been experiencing an issue with Flash CS6 for a while now when writing AS2 (no, I can't upgrade to AS3; the tool I'm developing for only supports AS2). When I publish my project, I'll get random compile errors in places I didn't even touch since my last compile. When I look at the code, a few characters had gotten deleted. At its worst, a few lines get deleted.
As you can see on the attached image, two characters got deleted from the middle of the line.
This has happened on numerous occasions, but not frequently enough for me to know what similarities occur between the projects.
Any ideas why this is happening?
i doubt there's a problem with your code. it should still execute as if it's there.
the problem is a font/graphics problem. try updating your graphics card drivers and change the actionscript font.
