Jason, sorry for the delay.

I don't fire up the yahoogroup very often, and the thread got hidden under another topic.

No, I'm definitely not saying that things are not working as they should :) IMO it is up to you to decide.

I can confirm this though;

I fire up my older (IBO native) app and select two records from a detail, then navigate to another master and select two more records. When navigating back and forth IBO remembers the four selected records.

Then I have a command "Unselect all rows" that calls detailDS.SelectAll(false) and that will "only" unselect the two rows of the current master record. When navigating to the other master with selected details they are still selected (two rows in total by now). I always assumed this was by design and catered for it.

IMO when calling SelectAll(true) on a detail the most logic thing is to select the "visible" records (?). Thus, SelectAll(false) should do the same. But I never used SelectAll(true) on a detail, so I can not confirm the behaviour there.
