It's probably showing you the formating.  Is there a paragraph marker at the end, it looks like a reversed P?  Look for the reversed P on the toolbar, that should toggle it on and off.  Or go to Tools-Options and on the View tab (I use Word97 so it might be different in later versions)  look for a section for nonprinting characters and uncheck the all box.
Hi,  I'm not sure what has happen with my word, but when I use it , every time I press the space bar when typing in a document a period shows up instead of a space. Can anyone tell me whats going on & how I can fix it. I only use word every now and then, so I don't know a whole lot about the program.  Thanks for the help.   Eml
