LINUX IDE freezes when started

IDE will cause a system freeze when started.

OpenJava will not work @ least version 1.7 dose not. IDE will cause a system freeze when started. I removed Openjava & I installed Oracle 1.7.0_12 and it works better but still freezes up often Also I used 1.03 version of IDE.
