Known issues with this security updateAfter you install this security update, you may experience the following issue:
On certain websites, when you use the Select All option in the shortcut menu, or you press Ctrl+A to select all content, and then you try to paste the content into a webpage in Internet Explorer, nothing happens. The content is not pasted. For example, the issue may occur when you try to paste the content into an Outlook.com message or an Outlook Web Access (OWA) message.
This issue may occur only on some websites. This issue occurs only when you paste into Internet Explorer. This issue does not occur when you copy from Internet Explorer and then paste into other applications such as Microsoft Word or Microsoft Outlook.
This issue occurs if the webpage contains a script tag, an object tag, or an embed tag that appears after the body tag.
To work around this issue in Internet Explorer, use the mouse instead of the Select All option or Ctrl+A to select the text that you want to copy. Try to copy only the section of content that you need instead of selecting all the content.
