Clickable widgets placed inside a stack must be clicked twice to trigger them

This can be seen in the Choose Scenario dialog, which uses clickable text widgets.

Actually, you can also click widgets in a stack once, then click any other widget, and the first widget will be triggered.

i.e. Click Start Scenario -> Click VoDT -> Click Cancel, and it will launch VoDT.

This makes no sense... in the debugger, control flow simply skips out of a function before it's complete.
