I answered my own question. The key was using NotebookClose, not
DialogReturn[].
And, since I have far too much time on my hands, here is some code to create
a dynamic flower that should look familiar to Mac users. Along with an
example of how to use it:
myflower := Module[{w, bigD, d},
w = .22;
bigD = 2;
d = 1;
Dynamic[
Graphics[{
Rotate[
Table[
{GrayLevel[Min[{1 - (i/(2*\[Pi])), .8}]],
Disk[{bigD*Sin[i], bigD*Cos[i]}, w],
Polygon[{
{d*Sin[i] - w*Cos[i], d*Cos[i] + w*Sin[i]},
{bigD*Sin[i] - w*Cos[i], bigD*Cos[i] + w*Sin[i]},
{bigD*Sin[i] + w*Cos[i], bigD*Cos[i] - w*Sin[i]},
{d*Sin[i] + w*Cos[i], d*Cos[i] - w*Sin[i]}
}]
},
{i, 0, 2 \[Pi], 2 \[Pi]/12}
], -Clock[{2*\[Pi]/12, 2*\[Pi], 2*\[Pi]/11}, 2]],
White, Disk[{0, 0}, d*1.1]},
ImageSize -> {250, 250}
]
]
];
mydialog = CreateDialog[myflower,
Modal -> True,
WindowTitle -> "Working...",
WindowSize -> All,
WindowMargins -> Automatic,
Background -> White];
nd = 1;
While[nd < 10,
Pause[1];
nd++
]
NotebookClose[mydialog];
I hope someone else finds this useful too.
