Access denied? Never heard that. Is your Windows user name somehow restricted?

Good hint, thanks for the link. I could try that:

while not Success do
try
  //Set the clipboard
  Success := True;
except
  on Exception do
  begin
    Inc(RetryCount);
    if RetryCount < 3 then
      Sleep(RetryCount * 100)
    else
      raise MyException.Create('Cannot set clipboard');
  end;
end;

The crux is that this is not in HeidiSQL itself, but in SynEdit. There is still some sporadic activity in the SynEdit project but I highly guess they are not fixing bugs anymore, so I'll give it a try and keep the fix in Heidi's copy of SynEdit sources.
