IE Tab is a Chrome extension that some companies use so that certain systems (e.g. Microsoft CRM) can be used without leaving the Chrome browser.
When you try to share a tab that contains the IE Tab plug-in, only the address bar from IE Tab will be shared, and not the remainder of the contents of the tab. At the moment, there is nothing we can do about this due to the nature of the implementation of IE Tab and of the underlying Chrome platform.
As a workaround, you may choose to share "Specific window" and share the entire browser window containing the IE Tab. This will work correctly, sharing the whole window including any browser tab you switch to.
