With a Cited By tool already open in the main Verbum window, in a secondary Verbum window, I click on the Information tab. Then I click the "New tab" button next to it. I find the "Cited By" tool and click on to open up a second Cited By tool. Crash every time. If I close the Cited By tool in the main window, it does not crash. Here are the logs.
