"NativeInterface.runEventPump()" must be called only once, at the end of the main method.

The "invalid memory access" sounds like a bug in the native runtime and there is little I can do if the native runtime is buggy.

The only thing we can hope for is to have improved statbility with the coming versions of: SWT 4.3M6 and Java 7u13 (which should allow DJ Native Swing to work on Mac with Java 7).
