IB_LookupCombo inherits from TIB_CustomCombo and TCustomEdit.
Somewhere up there, there is a Modified property, which according to the
help is set to true when the text contents of the control is modified.
This poperty is not set to true in the descendent IBLookupCombo when it
closesup with a different displayedfield contents than when it opened.
That is all..
Don't struggle... that's our job :-)

The inherited property of what?

I think the Modified property of the polling key column is the right one to
go for. If you try to use, say, the AfterScroll event of the lookup
dataset, you won't be certain that the user actually modified the polling
column unless you test it as well, each time the lookup dataset's buffer
pointer moves.

I must say I'm struggling here to ascertain what your problem actually
is...what do you need to catch?
