> What steps will reproduce the problem? Run Program Normally > What is the expected output? What do you see instead? ActionScript Code , see blank screen instead > What version of the product are you using? Is it "nightly build"? Which operating system do you have? Latest Version , Mac High Sierra > Please provide any additional information below. If the problem is related to a SWF file, attach it here, otherwise we can't help you. I got rid of all my java SDKs, and reinstall Java 10 SDK since then this problem has happened.
Using Java 10, could be cause of the issue ?
We tested FFDec on Java 8, we do not know how it behaves on java 9 or 10, so yes, try java 8. Also we do not test much on Macs so hope its not a Mac related problem. Also I know that first script after opening FFDec usually stays blank, it fixes when you switch to another script/treenode.
Thank you for the quick reply Proof of concept gif/mp4 : Have yet to figure out how to make faded jar use java 8 instead of 10.
Executing the following command in terminal : /usr/libexec/java_home -v 1.8.0 --exec java -jar ffdec.jar got it to load the action script located in the swf file.
Hi, I tested it a little on Java 10 now and yes, the scripts are not visible in there. I will investigate and try to fix it later, since most of the week I can't access my main computer.

Hello, No problem. Again thanks for the update!
Hi, I did some changes and it looks like the editor shows up in the latest nightly build for Java 10, you can try it.
