Need to do a simple Left Click in a text box

Hey guys, I have a situation where I have some simple text boxes where I am entering text. However the boxes are "required" fields, and for them to pass validation the page needs an actual mouse click in the box. I've noticed that selinium inserts the text into the boxes OK, but it seems to do it with out actually executing a mouse click in the box. I've tryed click, and atClick, and neither one seems to work. Any ideas appreciated...thanx!

maybe helps something like this:
@selenium.mouse_down("theTextbox")
