I'm glad you are raising this issue...

I believe there have been some changes in the sorting of NULL columns. Or,
at the very least, the ability to influence the sorting of NULL column
values.

I have not as yet made IBO fully aware of all the various NULL sorting
options. This will cause null values to have a potentially problematic
effect on incremental searching.

I'll add this to my list of issues to look further into. At the very least
it should be documented as a limitation of IBO.

Thanks,
