Copying files in eclipse was failing & creating a Snippet.java

When trying to copy a file from one project to another instead of copying the file it creates a file Snippet.java with the file name inside a main method.

WTF?

I did not suss out when this started & I have struggled to solve the issue.

Today I sussed it with some help from the wonderful stackoverflow.

Bizarrely the cause was the Skype 'Click to Call' extension in Chrome.

The stackoverflow solution suggests an upgrade to the extension might fix it but as I do not use skype from my work PC I simply deleted the extension
