How do I access the full text of an error in SSIS GUI?

I have an Excel task which is providing error text through the GUI, but I don't know how to access the error task without the GUI and the error disappears if I move the cursor from the X

I have the project property Run64BitRuntime set to False (though it is not editable so even if I wanted to, couldn't change it to true)

Design-time errors, warnings, and informational messages show up in the Error List pane, which can be shown by going to View | Error List.
