Crazy thing happening with Arabic Lotus Notes client

I’m working on a project with an Arabic version of Lotus Notes (6.5.2) on Windows 2000 with the server being Domino 6.5.2 with the Arabic language pack. When the client opens up their mail file (with either Domino Web Access (6) or Mail (6) template), the action buttons have question marks as the first item. When I open up that same mail database from a US Notes client, the Arabic in the cascaded action bar items look fine. Any thoughts???
