Explanation: It is Tkenv that duplicates the messages (in fact it stores a copy of each message sent), for a feature that was introduced in 4.5, during the Tkenv redesign.

In version 4.5, the "Log" view (bottom part of the Tkenv main window) has been improved significantly, and beyond the old "Log" page it also has a "Messages" page. The "Messages" page shows the messages sent within submodules of the selected compound module. Moreover, if the user selects a line in it, in the Object Inspector (bottom left) it will display the given message in detail, and every field can be inspected. With this feature, one can virtually use the "Messages" view as a protocol analyzer, can browse through the past traffic in that module at any time, and examine each message in detail.

One can configure the size of the event history (LogBuffer class as Korbinian discovered) in the Tkenv Preferences dialog. Old log entries are discarded, together with the duplicate of the old messages.

The bug is that those private copies are reflected in the message statistics too. They should not.
