Hello Jason, I have just finished develloping a fairly complex Java financial application using Jbuilder 2 on Win NT. I have used exclusively the latest Swing components (such as JInternal Frame you just wrote about). I must ask you one advice: I would like to port it to Linux using Blackdown JDK. How difficult will it be? Generally speaking did you run into uncompatibility issues betwenn Sun JDK 1.1.6 and Blackdown JDK? Than you. Pierre
