Words that cannot saved in Notepad

Notepad is the standard utility to create the simple document in windows,besides Wordpad. I prefer choose this program to the small case rather than other program similary.

This program also has expanable other function needs. ex: to create html website, create system registry, movie subtitle, DOS command, etc.even Viruses can be created by this program. ^.^

But did you know, thats some secret in Notepad, which some text cannot be saved there? :D

If you're not sure, just try to type this text in your blank page in Notepad: bill fed the goats then save the file. Now reopen this document and see what happens... :D 

The other words that can't saved: bill sux dog dicks  <
Now, you will able to guess somethin, WHAT or WHY the words couldnt saved. is just because remember WHO is the people behind this name >>. "Bill" (Bill Gates)
