Issues on PagePicker engine

1) with firefox 3.0.7, there are some js erreurs (screenshot)
2) the html table doesn't continue until the end of the engine (ie6 and FF3) , stop at column pid
3) the icons displayed at Title column of the page picker when callling that from create page engine /option 'moving an exsiting jahia page ' or 'linking to an exsiting jahia page' are not the same, why in second UI we don't have the same icon that we have in the first one? (screenshot)
