While trying to install a custom dialog I received a pop-up message that said the dialog was installed.
However, the message was too wide for the monitor to show how to acknowledge/dismiss the pop-up.
At first I used Task Manager to stop it. When I restated SPSS there was a pop-up about "unexpected error", but I did not see how to attache a screenshot.
Escape turned out the be the way to escape the pop-up!
SPSS 27, Windows 10 Home.
