Can you provide an ODBC trace for the text case?

I installed a trial copy of 4D on OS/X but was not successful -- one is 32-bit 
and the other 64-bit.

Sounds like the same problem I just reported as issue 296.  If it is, then what 
happens is that row 1001 contains a text longer than 19KiB (and apparently the 
first 1000 are smaller than that), which causes a NULL return that is 
misinterpreted as "no more data".
