VoxSpell User Dictionary Malfunction from the Context Menu

VoxSpell version 1.0.7 apparently does not correctly implement the context popup menu. I enable VoxSpell and highlight a misspelled word. Then I right-click the mouse and select "Add -" from the popup menu to add the word to the user dictionary. Then underlining is removed from the highlighted word and all other instances of that word in the document. The user dictionary does not change and if I close and restart jEdit, the previously added word is again marked as misspelled.

On the other hand, if I select VoxSpell from the Plugins menu and then select Add Word, the misspelled word is apparently added to the user dictionary as expected.

I'm using Java version 1.6.0_17 and ErrorList 1.7 with jEdit 4.3pre18.
