I thought he was referring to the Windows size grip--the one that you get when you put a status bar Common Control at the bottom of your window and give it the SBARS_SIZEGRIP style.
There is a white grow box for me in the lower-right corner when I use the X11 driver. He must have been using a different WM than the default quartz-wm.
If my diagnosis was inaccurate, then I wonder why he really couldn't resize the windows by dragging the corner... I don't have trouble resizing the windows, either.
In the case that the window doesn't have its own grow box, though, it can be hard to tell that you actually still can resize the window by dragging the corner. (In notepad's case, it's weird, because I can click and drag the Down button on the scroll bar to resize the window. It happens to be about where the native grow box would have been drawn if it weren't turned off.) On Windows, resizable windows have at least a thicker frame (THICKFRAME style), and they usually also have the CLIENTEDGE and WINDOWEDGE extended styles (giving the appearance of a frame that you can grab and drag to resize the window). The Quartz window server precludes that with its pixel-thin border and insistence that you grab the lower-right corner--at least, prior to Lion. That's why I suggested changing the cursor to SIZENWSE at the lower-right corner. I should really write a patch that does that :).

You can have everyone else draw into an IOSurface, and then share the IOSurface with Explorer (which I assume is responsible for managing the desktop window). You can even use an IOSurface as a GL texture (and, by extension, render with OpenGL into the IOSurface). This is how Chrome (and probably Safari too, since it uses the same underlying engine) implements sandbox'd rendering: the renderer draws the page into an IOSurface, then the browser draws the IOSurface into the window. And yes, this will work on Snow Leopard.

Guess I'll get right to work on that ;).

>>> More items can be added to the menus easily enough. However, I'm loathe to assign the usual keyboard shortcuts. The problem is that the Command key is used to generate Alt keystrokes and it's relatively likely that a Windows program will want to receive Alt-H for its menus.
>> Why aren't we using Option as Alt? Nearly every Mac keyboard labels it as "Alt" these days. Is typing characters like 'ü' and 'ø' and '∆' really that important? :)

Yeah, I'm joking. I realized just how silly taking that away would be as I was typing.
> but, yes, accessing additional characters from the keyboard layout is important. CodeWeavers' experience with support requests actually strongly influenced my decision to reserve Option for that. I'm open to introducing a registry setting to allow that to be changed.
If we introduce a registry setting, should we also add a Control Panel (something akin to Windows' Keyboard applet) or Preference Pane or something to change it? And if we do, we may wish to include a Character Map (charmap.exe) utility so users can insert additional characters anyway.
> And, yes, it sucks that the key is labelled Alt but can't be used as Alt. :(
While we're on the subject of bugs: another annoying problem is that, when a window is first created, the view appears black, and then the contents are filled in. This happens even with minor windows like menus. (It happens with the X11 driver too, just less often.)
