not working as expected after submission

hello
none of my forms are working properly
after submission (as guest)i used to receive a pop up success message.
once i had to create new thank you pages to measure activity of communications.
if i remember correctly, the forms used to clean the fields after submissions. they dont anymore.
after the latest update of forms component i have noticed (in some cases, not all) that the admin enviroment of forms freezes and does not respont not even to hovering the mouse over the about(to see version).
anyway...a little bit of help please.
thanx
