Original GitHub issue: https://github.com/rivo/tview/issues/635

My personal project reads input from stdin. However I'm noticing that certain actions, like Ctrl-C, need to be pressed again before the effect can take place.

For example, with an application like box demo in the wiki:

package main

import "github.com/rivo/tview"

func main() {
	box := tview.NewBox().
		SetBorder(true).
		SetTitle("Box Demo")
	if err := tview.NewApplication().SetRoot(box, true).Run(); err != nil {
		panic(err)
	}
}

If I compile it and run the following, the application comes up but my first attempt at Ctrl-C does nothing.

$ go build -o box-demo main.go
$ echo hi | ./box-demo

No big deal, just curious 🙂

For me,

go build
echo hi | ./box-demo

terminates with a single Ctrl + C. Which OS are you using?

@rgrannell1 I'm on macOS (11.5.2), but the issue seems to have resolved itself when I bumped the rivo/tview library.
