Ah yes, ok, thanks.
Just one final comment / critique (not trying to start a flame war): I think it is terrible OO design to have the Window (or now Display class) updating the Input system automatically. I have a lwjgl app that is updating the input system when I didnt even import the input package. Just imagine the rude shock I get when I find that just by initialising the lwjgl renderer, it is mucking up my current input implementation! The naming is misleading (what does Display have to do with input at all?), and nothing is mentioned in the JavaDocs. What im saying is, If I want to use the input system, I should have to explicitly say so in my code.
Just my two cents.
