I googled this, but I cannot get a decent answer as to why this is happening.

The MSDN documentation says that this often happens when the user switches to another application, but it does not appear that this was the case.

Solution

  • Having a similar problem. Found this entry, which basically says to set retryTimes to 2 in the call:

    Clipboard.SetDataObject(object data, bool copy, int retryTimes, int retryDelay)

    Going to try it. Would be nice if anyone could post a reproducible test case.
