[quote='Gord Dibben[_2_];1600898']This can be caused by the Skype Click to Call add-on (version
5.1.0.9560) that is installed into your browser when you install
Skype. Version 5.1.0.9560 has been known to cause the following
issues:

You use Copy in Excel, Word or PowerPoint and it only pastes Text.
Formatting is lost.
You use Cut in Word or PowerPoint and it only pastes Text. Formatting
is lost.
You use Cut in Excel and it performs a Copy and Paste as Text. The
original information remains and the pasted information loses
formatting and formulas.
When you use the right click menu to Paste, the Paste options are
limited to Text.
When you attempt to copy formulas in Excel, Excel only pastes the
values.
When you attempt to click on the Format Painter button in the Ribbon,
it does not work.
When you attempt to drag and drop cells within Excel, an error message
displays "The Clipboard cannot be emptied. Another program might be
using the Clipboard."

Skype has released a new version of the Click to Call add-on that
resolves this issue. You can download the newest version by clicking
on the following link and then*clicking the Download Now button:

I've managed to find similar info yesterday evening, and uninstalled Skype click to call feature. Ecverything went back to normal.
Thank you anyway!

However, since I don't use CLick-to-call at all, I won't be looking for newer version.

Think this thread can be closed :)
