I"ve thought i have noticed some strange behavior after compiling. most of the time i compile the class files update with my changes. Now and then i feel i need to delete my class files in the folder and do essentially a rebuild all to make the program start working properly. Are there cases where the class files running are not the ones you think are running or it doesnt write to them all or the class loader picks another class file with the same class in it even though its scoped differently like frame$ball.class vs frame$panel$ball.class.
