So for any errors that happen in "window", do "null" or absolutely nothing. This line should only be used once you are absolutely sure you are done debugging your code!

This will kill the error messages if someone tries to mouseover before the images are done caching. FYI. Pat Richard Web weenie http://www.gurusnetwork.com ICQ 23113317
