>When I first came in this morning:

There is one more setting in regards to that. By default, it would be as I described when the treeview goes dynamic. Thus, this is like that when the number of messages is greather than the number of messages defined in "Account setup/PUTM/Settings/Map of messages settings/Number of messages before the treeview goes dynamic" is reached.

This means that you can decide to have it exactly as you want by diminishing the value of that setting. The minimum is 50 however as there wouldn't be that much need to go lower than that.

So, if you put it at the minimum, thus 50, as soon as you have more than 50 messages to be shown, it would be as you want. This setting applies to new messages and any other map of messages.
