Can't view my work while using the Liquify filter

[greeneggs28]

I'm currently following a tutorial on how to make smoke in photoshop. I'm using Photoshop CS2 on a MBP 2.4. It's rendering very slowly when entering the Liquify filter mode (which seems to be a normal thing with most users after reading entries here about that specific filter). But when I try to use the "forward warp tool, spiral tool, etc", I don't see anything happening, not even when turn the pressure up. It is still very difficult to see anything. But when I apply the filter and exit the filter mode, everything I did in the Liquify filter becomes visible.

Is there a preview button I am missing? Any suggestions appreciated.

Thanks

Create low resolution copy of the file you wish to liquify.
Run the liquify filter and make the adjustments.
(It should be far more responsive than with the high resolution image.)
Click the "create mesh" button.
Click OK to dismiss the dialog.

Now switch to your high resolution image, run the liquify filter, and choose load mesh, click OK.

Are you loading your entire image into Liquify? It will help a lot to use the selection tool to isolate the portion of the image you want to alter beforehand, then Liquify it.
