The thing to learn is that the hotkey (ALT + m in Win on a selected
method) reuses the window but the button open new ones.
And for senders (ALT + N) you have to use the list and not the code pane.
Which I' reminded to every now and then because only very seldom I use

If you turn it on, then you get MessageTrace browsers in response to cmd-m/n and so on, but the code in MessageTrace>browseAllCallsOn: (etc) doesn't seem to be used. Even stuck breaks in there to see if I could catch it. That seems a pity; all that work to write MessageTrace and it can't be used?

A MessageTrace is built (I trapped that ok) but if I ask for implementors or senders of any method in the list I get a separate browser rather than the added methods in the same list. If I toggle break in MessageTrace>browseAllCallsOn: it never gets run.

Click on the ‘implementors’ button - the browser that opens has a model that is a MessageTrace. That seems to demonstrate that the preference is actually ‘true’. Click on ‘senders’ in the method browser & choose one of the menu of selectors. I expected to see the senders added to the method browser.
