Bush hid the facts...Why this happens ?

1.) Open an empty notepad file
2.) Type "Bush hid the facts" (without the quotes)
3.) Save it as whatever you want.
4.) Close it, and re-open it.
See what happens, isn't it a weird bug?

Reason:

This doesn't happen only with "Bush hid the facts".
It also happens with "Love bug bit fayaz". In fact it works
with any 4 words with 4, 3, 3 and 5 alphabets.
