Summary0004411: TjvSimScope crashes with a divide by zero error.
DescriptionThe easiest way to reproduce this is to add a jvSimscope component to a form.
Set the property Active to true.
Add a jvScopeLine via the properties.
As soon as it is added you get the error. The only way out is to try and delete the scopeline during the interval or end Delphi via the task manager.
Additional InformationThis can be resolved by changing the following function from:

function TJvScopeLineValues.GetItem(Index: Integer): Integer;
  Result := FValues[(Index + FZeroIndex) mod FCount];

Change To:

function TJvScopeLineValues.GetItem(Index: Integer): Integer;
  if FCount = 0 then
    Result := FValues[0]
    Result := FValues[(Index + FZeroIndex) mod FCount];

It is not a perfect fix as it leaves a gap in the scopeline, but it works.
