Hopefully this hasn't been addressed elsewhere in this forum and I just
missed it.

I am using JavaScript to switch buttons (onmouseover,etc.).  The only
trouble I have is that the first time an image is switched it causes a small
misalignment (5-10 pixels of white space directly below the new image).
Upon resoration of original and all subsequent switches everything aligns
perfect.  Any ideas how I can fix this annoyance?

Thanks for any help!
