  (where 'ptr' is what you get from the pMarksAccess->makeNoTextFieldBookmark()
call before casting to anything)

Okay, managed to put in some debug
here the code snippet(s) were the debug was done ( same for distro/no-distro except for some text to distinguish one from the other )

                rtl::OUString::createFromAscii( ODF_FORMCHECKBOX ) ) );
        IFieldmark* pFieldmark = dynamic_cast<IFieldmark*>( ptr );
OSL_ENSURE(pFieldmark!=NULL, "hmmm; why was the bookmark not created?"); 
        if (pFieldmark!=NULL) {
IFieldmark::parameter_map_t* const pParameters = pFieldmark->GetParameters(); ICheckboxFieldmark* pCheckboxFm = reinterpret_cast<ICheckboxFieldmark*>(pFieldmark); OSL_TRACE( "distro ( Read_F_FormCheckBox ) %p %p %s %p %p %s %p %p %s reinterpret %p %s\n",

docbm.cxx ( MarkManager::makeNoTextFieldBookmark )

        sw::mark::IMark* pMark = makeMark( rPaM, rName,
                IDocumentMarkAccess::CHECKBOX_FIELDMARK );

and the results......

disto 32-bit
============

(interesting in the library the implementation is in the dynamic_cast works )
distro 0x8d013a4 0x8d01370 N2sw4mark17CheckboxFieldmarkE 0x8d013a4 0x8d01370 N2sw4mark17CheckboxFieldmarkE 0x8d013a4 0x8d01370 N2sw4mark17CheckboxFieldmarkE reinterpret 0x8d013a4 N2sw4mark17CheckboxFieldmarkE 
dynamic_cast<ICheckboxFieldmark*>( ptr ) (nil)
( and here it doesn't so I guess there is some symbol confusion.. but I don't see it )

does anything here stand out? ( /me is not that up on library symbol binding, visibility etc. stuff.... must read more :-) )
