As always, I have been having promblems with tekkit classic.

As you can see, my screen is not centered and upside down. When I put into full screen using F11 my screen goes black and I am unable to do anything except move the mouse. I have to shutdown my computer to exit the fullscreen state.

My computer is quite old though, It is a Mac running OS X 10.5.8. If anyone has a solution or a similar promblem, please post something here.

Thankyou in advance.
