Greatly reduced action performance in CS5

******BUG******
Concise problem statement: reduced performance in Action processing in CS5 compared to CS3
Steps to reproduce bug:
1. Create an image file, 8000 by 9880 pixels 16-bit RGB color.
2. The background can be any image, though I was using a scan of a test target with colored patches for scanner calibration.
3. Create a layer "final target" on top of the background. Set contents to transparent.
4. Create a selection 295 pixels on a side with rectangular marquee tool. Position this selection in the upper left corner.
5. Save the selection to an alpha channel "Grid Box."
6. Run an action with the following steps.
a. Load the selection "Grid Box."
b. Select the layer "final target"
c. Expand the selection 2 pixels.
d. Fill the selection with the foreground color.
e. Set the foreground color to white.
f. Select the background layer.
g. Move the selection 295 pixels to the right.
h. Save the new selection as "Grid Box", replacing the channel.
The use of this action:
Use the eyedropper tool to select a color from the center of the selected square, then use the magic wand tool to subtract from the selection using the color in the center of the square in contiguous mode with tolerance set to 8. Then run the action, and repeat the above process in the next selected square. In the scan I am preparing, there is a grid of colored squares surrounded by a large black border. The final result needs the black border eliminated so that the colored squares completely butt up against each other spaced 295 pixels apart.
So by running the action, the color in the center of each box is copied to fill the rest of the square selected area that's black, leaving the center portion intact. The copied colors go on the "final target" layer so the background layer is not disturbed.
If you need a copy of the action and/or the image file, contact me by email.
Results: In CS5 the action is unusable due to the long run time.
Expected results: In CS3 it works perfectly.
