jquery mobile and search form

jquery mobile and search form

Hello,

i've got a problem with a simple form (post or get) :
When I arrive on a page and I submit the form the page never stops loading and i must close it, impossible to do something else, it loads... but If I refresh the page when I arrive on it and I use my form after the refresh it works.
If I deactivate the ajax it works fine ('$.mobile.ajaxEnabled=false;).

I tried a few things and the problem is the page in which i submit the form and not the action page.
Notice that I never have the problem on some pages, and the problem always appear on others.

I had a similar problem with the display of a few divs (and working if I deactivate ajax)  and I solved it using the jquery popup instead of my divs, but in this case I don't know how i can change (it's a search form in the top of the template of my website)

has someone got a solution ?
