Lately, I have been unable to log on to KLM using IE (11), as the Captcha check box does not appear. But I can log in using Firefox.
I find that more and more website designers/programmers are becoming 'lazy' these days - it's all to easy now to blame IE (or Chrome) for being non-standard. These guys should man up to the task: websites should work with whatever browser the users prefer ... and they should be tested!
