I had this problem before and it was fixed by support. I then upgrade EasyDiscuss and the problem returned. Support gave me this code to put in custom.css as as a solution, but it does not work. Can you take a look at it again please. The solution below provided is currently at the botton of the custom.css folder in the backend.

--------------------------------------------------------------------------------------------------------------------------------------------------------
Please place this in custom.css with in your template folder,

div#discuss-wrapper .discuss-searchbar .discuss-searchbar--right {
margin-top: 0px;
}

if that did not work and something is overriding add !important behind you parameter's value:

div#discuss-wrapper .discuss-searchbar .discuss-searchbar--right {
margin-top: 0px !important;
}
