I tried CHMOD, updating, simple terminal line commands and nothing seems to work. When I try install NetBeans 7.3 the screen is blank and if I try to do something it gives me the error that states the application will close and asks for a force quit option and says all progress will be lost. Any ideas? I have been to both the NetBeans forums and asked as well as the Java boards which directed me back to NetBeans forum page.
