In the latest Squeak6.0alpha-21736-64bit (64bit MacOS) I did the following:
SystemNavigation default browseAllImplementorsOf: #isTTCBased.
I clicked the button senders in the message list browser.
I chose isTTCBased in the list.
The senders are inserted above the implementor of #isTTCBased.
When I select one of the senders the window title stays "Implementors of isTTCBased“. Shouldn’t it change to "Senders of isTTCBased“? Normally, selection of different methods in the message list changes the title accordingly.
