TMSFNCChat go to last message

Hello,

After added a message I want to show it.
I manually add message with :

NNewTTMSFNCChatItem:=TMSFNCChat1.AddMessage(AQuestion,cmlRight);
NewTTMSFNCChatItem:=TMSFNCChat1.AddMessage(AReponse,cmlLeft);

But how to go to the last message (= vertical scroll in bottom) because this doesn't seems to work fine when messages contains multiline text (10 lines for example) :

TMSFNCChat1.ScrollToItem(TMSFNCChat1.ChatMessages.Count-1);

Sample :
Scroll.zip (2,3 Ko)
BadScroll

Hi,

Thank you for reporting this, we'll investigate.
