Repeated Warning When Saving .TXT File

[Mr.Bumble]

Hi,

Sometimes I like using Word (2007) to compose a .txt file instead of opening Notepad. In such cases I have gone so far as to set Word to save files as .txt files in the settings. The problem is that when I start composing my draft (or begin editing one) and click Ctrl+S to save it (which I often do by habit, despite auto-save being enabled), I get a warning message. This happens every time.

Is there any way to turn these types of notifications off ? I've searched Word help (and will continue to do so) and have searched online but have found nothing to help so far. Any input would be appreciated.
