someone advise me of the outcome/solution, as we are having the same
problem. I have browsed the archive, but have fail to find a reply.

We are using BCB 5 and have the same issues.

The post mention that using last and first was a work-around. However, when
we try this work-around, we are not seen the required behaviour.
