Bobcad is adding even more tutorials and FAQs on their support forum for V22.
This also includes info on Vista.
Also one Vista issue that may cause problems due to adminstrator rights has to do with Vista login. This is not a Bobcad issue but could cause a problem running Bobcad or other programs that require hardware connections.
Make sure you set a password for logging into Vista. It does not matter if you are the only user. You can change the password back to a blank password in the same way you set one but you must initially set a password before Vista allows certain functions to run as an administrator. So if you have never set a password give it a try.
