Hi
This has worked for me in the past.
1. Press the SHow/Hide button on your toolbar in order to display all the control characters in your document.
2. Press Ctrl+A to select the whole document.
3. Press Ctrl+Shift+Left Arrow (this has the effect of deselecting the last paragraph mark in your document which contains all of the formatting of your document.
4. Press Ctrl+N to create a new document.
5. Press Ctrl+V to paste your text into a new document.
6. Save your document and then check the file size.
Hope this helps.
Good luck.
Tony
