Well apparently your pic on the main page is a earlier version and you have all your options right there in the opening window. In this version I just downloaded it is not like that. I have to click on the Options Tab ( which you don't even have in your pictured version) then I have to click on the keywords tab within the Options tab and search from there - not nearly as convenient seems to me as the version you have pictured. Could I get your version? lol  Anyway, maybe you should change the pic of your program so other dumb people like myself won't get confused :)

Ok I'm feeling stupid - I must be missing something obvious, but I just don't see it. I have no search area ????? (see pic)
