If you need support from Yola please contact us via firstname.lastname@example.org or make use of our live chat service! We are working on a new approach to community-based support and during this transition period we are not adding any new threads to this forum. Many thanks to everyone who has participated over the years and we look forward to unveiling a new peer-to-peer support system soon!
Alex is correct, Windows 7 (operating system) doesn't have anything to do with how yola is run. The browser (internet explorer, firefox, safari, google chrome) is what determines how yola functions. Firefox is the preferred as I believe this is what yola uses to create and test the sitebuilder.
