Having just upgraded to Windows 10 and using te Edge browser, I noticed that clicking on smileys, link icons etc don't work.
Edge is a completely new browser by Microsoft. They claim it is and will be 100% standards compliant. But it already has issues. There are some things that work on all other browsers fail with Edge. The developer community is hoping that its just some teething issues and Microsoft will iron out bugs with time.
Everything on GMG seems to work fine with Edge (I posted this message using Edge) except the BBC and Smileys when posting.
In the meantime, I suggest using Chrome, Firefox or Safari, all of which work fine.
