JM Slideshow: Images go faster when minimize or open site in another tab of browser

<p>The slider seems to work fine when you first visit the page but if you leave the page open and open a new tab or minimize the page, AND THEN come back to it the slider starts to cycle through the images crazy fast. it seemed to me like the slider was winding up as odd as that sounds. for example the images cycle every 4 seconds, so if i tab away for 20 seconds the slider cycles through 4 images very fast then it continues normaly, if i tab away for 40 seconds the sliders cycles through 8 images really fast before going back to normal. The longer you tab away the more images that cycle through fast when you come back to the page.</p>
