Beta 91 on MacOS X 10.4.2

Here is code to illustrate:

// Teleporting MouseX off the left side of the screen


int x, y, h, w;

void setup()
{
size(500,500);
framerate(10);
}

void draw()
{
background(0,0,0);
x = mouseX;
y = mouseY;

h = mouseX;
w = mouseY;

if (x <= 0)
{
x = 10;
}
else if (x >= width)
{
x = width - 10;
}

if (y <= 0)
{
y = 10;
}
else if (y >= height)
{
y = height - 10;
}

rect(x,y,10,10);
println("x = " + mouseX + " y = " + mouseY);
}

this unfortunately appears to be an issue with how apple's implemented the mouse handling
in their java vm. this came up before and it seems to be specific to their implementation of
the event handling in java 1.4 versus 1.3.

of course, there's lots of weirdness for how components are handled, but since we're not
seeing this on sun's own implementation, we have to assume it's apple's bug.
