Having a bit of a problem with this editor.
As most of you probably know by now, I'm running Ubuntu Linux instead of Windows now, and decided to try the Java editor rather than attempt the nightmare which would be running the regular editor under WINE. (And no, I still haven't got the regular game working.)
The editor works from what I can see, however, it runs at a terrible framerate and takes up a lot of CPU (usage of both cores about 80%). This makes it nearly unusable to be honest - I have to wait about a second for the cursor to respond, and...yeah.
I know rather little about Linux, and even less about Java, so I can't really help myself with this.
By the way, my computer doesn't just suck, or anything - both of my processor's cores are 3.8 GHz. Also, other Java stuff runs great.
