If you want me to write you, what to do? I will just copy/paste my preview descriptions.
Nothing different, the principle is the same, how I already describe it.
You must create one new item to the chrono.
Over the chronometer.tga you measure the resolution and position of this new item, that will define the area, where you will click for the chrono to start/stop/reset.
Or, the easiest way is, just send me your menu_1024_768.ini and this chronometer.tga, and I'll do it.
