I'm using the Willow template on one of our websites and when we click the menu items in the top menu the slideshow image appears to be, very briefly, loading all or at least more than one, of the images in the showcase area.....it has a "jumping" appearance....I don't know how else to explain it. We've used this template on other websites and in checking we found it does it on all of them.....some worse than others. In checking the demo we noticed it does the same thing....not always but at least some of the time. The url of one of the websites we're noticing this on is dev.belgradelakesmarine.com. We've checked in using all browsers except Internet Explorer and checked it on a Windows computer and a Mac and it does the same on all of them. Any suggestions for a solution would be appreciated.

Thank you
