Vertically maximized window changing size when closing tab

I tried this on Windows 7, vista and on Linux.
If I have a window maximized vertically, then open a new tab (say :tab he)
and then close that tab, so the tab line disappears the gvim window loses a line.

I would like it to keep its original size since I had it vertically maximized to start with.

Is there a way of doing this, or may this be a bug?

Thanks,
Jorge
