difference between jquery1.1.4 and 1.2.6 with regards to my app


Hello,
I have created an asp.net (vs2005) web-app.
When i use jquery1.1.4, then, on submitting the form, the background
gets grayed-out and an 'results being generated' image (that i have
put in the asp.net code) gets displayed.
i replaced the 1.1.4 file with 1.2.6, and now the background doesnt
get grayed-out (aspnet code remains same) at all. The image gets
displayed but since the background isn't grayed-out/"disabled", the
user-controls kind-of overwrite part of the image.
My OS is XP/SP2. I am just starting to learn jquery, so don't know
much about it.
Any suggestions/advice/pointers?
Thanks.
