Arduino ide

Hi guys, i have a problem with arduino ide on windows 7 32 bit. When i try to write anything, it won't work and i can't copy or paste anything. I can only open the example schetch and upload it on arduino. How i can solve this?

In the preferences, make sure "use external editor" is not checked.
