Hi,
I‘ve changed the position of the search box for the site http://lumeaparalela.ro/ and when I'm using Opera 12 for Mac I canot type anything into the search box. However, it seems to work OK with all other browsers (though I didn't tried Opera for Windows).

position: relative;
border: #cccccc;
border-bottom: 0;
width: 326px;
margin: 0px 0px -38px 0;

thanks,
dan

It work fine for me in all browsers on Windows including Safari.

I'd say it is some opera bug - go into presentation mode (view->Presentation View) and it works fine.
try adding a ziindex: 99; to your rules.

juggledad, "z-index: 99;" worked great, thanks alot!
