Charts automatically being created in Excel 2013

[a1dreams]

I have just upgraded to MS Office 2013 on my work computer and am having an issue in Excel. When I have a row or selection of rows/columns highlighted and click Ctrl-C to copy, I am randomly getting multiple charts opening up on individual tabs. It also happens occasionally when I click tab or ESC - there doesn't seem to be a rhyme or reason to the issue.



I have looked in the options and cannot figure out what setting needs to be changed to keep this from happening. It is taking forever to work on data, having to go in and delete 100+ charts at a time that should never have been created. Any help would be greatly appreciated.

Thank you in advance!
