You can call the ActivateTab method on the control, like this:
Where sTabName is a string variable that is the name of the tab used when calling AppendOutput.
Tried it but it is not bringing the tab to the front. I can't get any of the tabs to react to this command. I'm assuming the ActivateTab method means bring it to the front as if you clicked on it, true?
