I, in fact two end users have seen a strange issue in Excel.
When they CTRL+X to cut some cells and CTRL+V to paste, it does copy/paste, not cut/paste
They said it is related to the new version addin I built. I do not use or change anything about copy/cut/paste in my code at all. I suspect it is some options in Excel, but not sure what it is.
Do anyone know how to fix the cut/paste issue in Excel?

Edit
my addin is written in C#, Excel DNA, NetOffice, Add-In express. It is a xll addin with ribbonX and also has UDFs. There is no VBA except during install/uninstall, I use VBA to install xll and xla.
xla returns descriptions for UDF and register help topics.

thanks
