Nice work

Can you see why I need to hit enter twice to return from suspend?

package main

import (
	"bufio"
	"fmt"
	"os"

	"github.com/rivo/tview"
)

func main() {

	app := tview.NewApplication()
	button := tview.NewButton("Hit Enter").SetSelectedFunc(func() {
		app.Suspend(func() {
			reader := bufio.NewReader(os.Stdin)
			fmt.Print("Enter text: ")
			reader.ReadString('\n')
		})
	})
	button.SetBorder(true).SetRect(0, 0, 22, 3)
	if err := app.SetRoot(button, false).Run(); err != nil {
		panic(err)
	}
}

This is a known bug. https://github.com/gdamore/tcell/issues/194

This will be resolved once the tcell bug is fixed. So I'm closing this issue as there's nothing I can do about this.
