so,
-check in windows Display properties if your windonws is in a 16bit/pixel mode. (65535 colors) (not in a 24 or 32 bit/pixel (millons colors).
If not, put it in 16bit/pixel. and try again.
then try to download and use the Jeston3_640x480 layout.
Check with AtomicManager that the resolution is set to 640x480 Horizontal.
Try again.
If it doesn't work , try the same thing but set the resolution to 320x200 . and Try again.
Let me know if one of this step works.
I don't think the problem comes from the windows scriptiing host , so no problem on that side.
thanks
