I'm using IntellijIDEA Ultimate Edition. Browsing .class files that compiled from java source code is easy: I can just double-click on .class file and IDEA will decompile it. 
However, with .class files that were compiled from scala source code it's not working. It seems that IDEA just referencing to the scala source file. 
I've noticed that IDEA behaves like that only with scala plugin installed. It works fine without it. Is there a way to decompile using IDEA without switching off scala plugin?
