Foundation Factory is another program that has blocks in it. Quilt Pro can load them in with your regular quilt pro blocks. There is also a Kansas City Star collection, Mariner's Compass, and several Carol Doak collections. There is also a free block of the day download (I do the last 7 every Sunday) and a free block of the month on the 1st of each month.
Yes, the latest patch/update/bug-fix.
http://www.quiltpro.com/update.shtml Click on whichever product you have, download & run. Quilt-Pro came out when most people were still running Windows ME or Windows 98. Windows XP was still the new kid so they have been freely updating to keep Quilt Pro running on the newer operating systems and as people find problems with certain printers, blocks, fabrics, etc.--they fix the bugs.
Poke around on the Quilt Pro website for a while.
