Recently, we’ve noticed an issue with Skype Click to Call that causes the Copy & Paste function in Microsoft Office to behave abnormally. We’ve just launched an update to Skype Click to Call for Windows, 5.11.4928 which fixes the Office Copy & Paste issue described in greater detail here.
You should receive a silent upgraded version of the Skype Click to Call browser add-on that is free of this problem. Or you can download it directly by visiting Skype Click to Call.
