I'm getting an error message on one form occasionally when I click on different controls while in the design mode of vb.net I copied a few controls, and don't know if this has to do with it. I've copied dcontrols before without any problems. The form runs in fine in development mode. The message is:

"InvalidOperationException: Cannot call Invoke or InvokeAsync on a control until the window handle has been created."

Any idea how to fix this, or what it means?

TIA
