Are the words you are trying to copy from an online soruce? If so it could be because the words on the website are in much larger format then what you think. What you could try to fix this, is either copy and paste something else and see if it works or if that doesn't work try copy and pasteing it into Notepad.exe first and see if it shows up as larger font. But if all else fails you could always re-install the program.
