table Z_* property id does not properly compare values

[samuelmolinski]

While I was trying to update my pages with some ajax I notice that the id numbers do not properly compare. For example when I received the tweet tagged with an id of "158926829690957824" I logically only wanted the next tweet following this. I resent using the $_GET of max_id. I adjusted by value of one to give me "158926829690957823" but still received the same tweet (plus the additional tweets as excepted).

This problem seems to remedy itself went I changed the initial value by 1000 (158926829690956824). I suspect a data-type problem.

This maybe caused but an incorrect data type in the DB (currently it is CHARVAR(100) maybe BIGINT would be better) a hiccup in the program somewhere.
