It may be a problem with the computers... I know you have Vista which could have different texts. I found out if you copy the squares into a document you can read it. [][][] becomes you. My suggestion to fix it for everyone is to change the text to Times New Roman. If it already that then I don't know...
Text bug is still happening. To clarify the text bug is just []'s instead of the letter with the numbers the same. I'm going to test a few things to see if it works.
