For those of you that use the Switched on Schoolhouse homeschool curriculum and have Windows 7, I have news for you! After several attempts to get our previous versions to work with no avail I finally called them this morning. They say the 2009 version will work but alas everything I have is older than that. But there is better news than that. On April first they will have a 2010 application disc and if you get it all of the previous versions back to 2003 will work! Yay! I was getting concerned that I was going to have to buy all new curriculum.
