Trouble with quote in quick search module

When performing a QuickSearch on a text field containing a simple quote (e.g., searching for %D'UN%), ScriptCase generates a corrupted SQL query by quadrupling the simple quote instead of doubling them.

Generated SQL Debug : Instead of producing ... WHERE field ilike '%D''UN%', ScriptCase produces:SELECT ... FROM ... WHERE field ilike '%D''''UN%'

Is that a real bug of Scriptcase module or may I have done a mistake when customizing my Grid?
