I just upgraded to Mac OS X 10.9 GM Mavericks. I also installed the latest JRE from Apple and Oracle and the latest version of Aptana Studio 3.
When starting AS3, the application appears without a menubar. There is only the main window.
Can I fix this somehow?
$ java -version
java version "1.7.0_04"
Java(TM) SE Runtime Environment (build 1.7.0_04-b21)
Java HotSpot(TM) 64-Bit Server VM (build 23.0-b21, mixed mode)
Aptana Studio 3.4.2.
It looks like there's a new version that fixes it, refer this page: http://www.aptana.com/news
The actual download link didn't work for me, I found it here: http://preview.appcelerator.com/studio/
