Selenium Ruby Webdriverスクリプトを実行すると、次のような問題が発生しました。
Seleniumがスクリプトの実行を終了した後、ブラウザーは閉じられます（これは予想される動作です）。ただし、直後にブラウザが再度開かれ、何もせずに閉じられ、継続的にブラウザが再び開かれて閉じられます。このことは、ブラウザ（FF16、IE9、またはChrome）が完全に閉じられる前に約4回繰り返されます。
以下のログメッセージは、ブラウザを開いたり閉じたりするたびに表示されます。@driver.quitを使用してブラウザを閉じていることに注意してください。この不便な状況を克服するために私がしなければならないことを私に教えてください。本当にありがとう。
