There was a problem with Quartz Extreme on machines with 2 different video cards when some users reported QE was disabled. I was lucky and I had the shadowed cursor on one display and 2D cursor on the other.
If you have only one video card, possibilities are:
1. You changed the video card after Jagwire installation.
2. You have installed some 3rd party OS modificators.
3. There is a problem with the card's drivers.
4. Some permission problem prevents OS from displaying the right cursor.
There may be other things which just don't come to mind.
Yeah, at one point, I had accidentally installed a driver update that I didn't need, and it disabled graphics acceleration (including QE). Quartz Extreme checker showed my display as not accelerated but I still had a shadow cursor.
So yeah. Your graphics card just doesn't support it.
Hey, where'd my shadow go? Oh wait, its still there. I had completely forgoten about it.
Its been months since i thought about the cursor shadow. I was a bit skeptical but apparently the shadow is so subtle that I don't consciously notice its there. I wonder if I'd notice if it disappeared.
-- Cursor shadows have nothing to do with Quartz Extreme. It is possible to have a shadowed cursor on a video card that Quartz Extreme doesn't support, and likewise, it is possible to have cursors with no shadows on video cards that Quartz Extreme does support
-- It has nothing to do with Carbon vs. Cocoa -- it is a system-wide thing that is dependent on the abilities of your graphics card

<strong>If you don't have Quartz Extreme, you don't have a shadow.</strong><hr></blockquote>
Not true. I have a 32 Mb Radeon on a 2x AGP port.
Quartz Extreme is active (I've checked), but I also have no shadow below my arrow.

how do you check if quartz extreme is active exactly?

It depends on your graphics card. Some models can do QE, but not the shadow. Or, ahem, vice versa.
OK, OK. I have no idea.

It happens that a large amount of these cards also support QE, but not all.
It was only in Jaguar that Apple added support for this feature of some cards into the OS. Thus the misunderstanding that it's somehow related to QE.
So yeah. Your graphics card just doesn't support it.

Dude, take a course in elementary logic. The first statement is 100% true.
"If not A then not B" does not imply "If A then B".</strong><hr></blockquote>
I almost said that, and decided against it. Thanks for pointing it out though.
(Now, by avoiding posting a semi-relevant message, I've instead posted a completely irrelevant one, oh well)

:eek: Oops. So I was wrong overgeneralizing things.
