Default Render window doesn`t open on `render`

[higgledyhiggles]

Using Standard Max Render Window, I`m hitting render and the render window remains closed (closed it after last render). I can reopen it while re-rendering which is nice but i`d have thought it should open automatically ? Not sure why you`d want to hit render ant not see it.
Tried it with Corona Render window and that opens automatically ok. So just the default one.
Using max 2013
(I know I should probably use corona window but still..8)

Damnit,
Ignore me I had it set to` none` not `default` !
