Right after starting a new game, I wanted to create a save file.  I started to give it the name shown in the first screen snapshot below, but instead of saying "This Is An Example" I wanted to change it to say "This is A Very Good Example".  To make the change, I positioned my cursor between the "A" and the "n" as shown in the second screen snapshot.  I then hit the "Delete" key to remove the "n" and then tried to enter a space and then type "Very Good".  However, the space key doesn't seem to work when inserting text.  What I got was what is shown in the third screen snapshot below.  However, if I use the arrow keys to position the cursor where I wanted the spaces, I can now insert the spaces as shown in screen snapshots 4 and 5.

This is a very quirky, but annoying issue.  The player should be able to insert spaces whenever and wherever they want when creating a file name.
