Sporadic Run-time error 4605 no clear purpose

Hi, I have a long module written to copy data from an excel sheet to a new word document.

I sporadically get the error message saying:

"run-time error 4605
This method or property is not available because the clipboard is empty or not available"
Stepping into debugger it stops here: "wdApp.Selection.Paste"

It seems to occur randomly (different places, different times and sometimes runs with no issues).

I have tried adding DoEvents and tried to use Application.CutCopyMode = False but still occurs.

Does anyone have any other ideas how to stop this error occuring.

Thanks for the suggestion.
I already had one DoEvent between each copy and paste command. I added one to before every copy as well but still causing the same problem.
There are approximately 120 copy commands in the code
Any other suggestions
