Please forgive me if this has been addressed in the past, butI tried a search and couldn't find anything on it.
When I run IDEA without an internet connection, I consistently get a javax.imageio.IIOException, could not load background imageerror for various screens. In fact, IDEA sometimes become unusable because the dialog box displaying the message refuses to quit popping up. As an example, attempting to change the method signature on a interface causes this to happen.
Now, this could be my own dumb fault because I'm running jdk 1.5-rc with IDEA 4.5.1, which probably isn’t supported, Nevertheless, If anyone has any advice, I'd be grateful.
