Am running Ubuntu 910.. When I am spellchecking notes, and I save a new word spelling, Gedit doesn't save it... What's the corrective code to make Gedit save my "custom word-spell saves"?..

In 910 Gedit sees don't, can't, shouldn't, and the like, as spelling errors..
I.E.: Gedit spellcheck sees "shouldn't" as "should" plus "n't".. citing the "n't" part as a misspelled word... Can this be corrected when save a new word doesn't save?.. "n't" as the misspelled word
