You don't need to update or anything. This is an known issue with the JVM on linux. You lose key stroke focus if you go to another window/application. I always had to right click inside the Netbeans window to get the focus back. This is irritating but it's a problem with the JVM, not with Netbeans.
I had this problem with all the versions of Netbeans I used. For php, Java SE, ME everywhere. -- *Abu Ashraf Masnun* Grad Student, BBA, Khulna University. http://masnun.com -- Ubuntu Bangladesh | http://ubuntu-bd.org [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bd
