I just downloaded the latest version of IntelliJ IDEA EAP Build 2139 and installed the latest Java SDK. Everything's fine except for the console window popping up when I run the program.
As for the threads on how to get rid of those, I've read through them.
If I open idea.lax, all the stderr, stdin and stdout properties are empty, e.g.
leave blank for no input, "console to read from the console window,
and any path to a file to read from that file
If anyone has time for tedious stuff like this I'd appreciate it :o)
