If you’re having problems getting the Style Designer to load it may be a known problem with “memory leak” with the Abobe Flash Player and Internet Explorer. I’m told it gets worse if the link is opened in a new window.
So, if you’re having problems go to the property website http://www.245encanto.com and choose “Interactive Style Designer”. Then click on the link about half way down the page “Click here to go to the Interactive Style Designer”. I changed it to load the tool in the existing browser window which hopefully will reduce the chances of running into the memory leak bug.
