I think I found a bug in the Edit control that is e.g. used by Notepad. To reproduce the bug do the following: 1. Create a new .txt file 2. Open it with Notepad 3. Write "aaaaaaaa aaaaa aaa aaaaa" without the quotes (other letter combinations also work but not all) 4. Close and save the file 5. Open the file again with Notepad Now you should see squares instead of letters. Maybe you can pass the bug to the responsible developer. Smiley
