Here's something to be aware of.
I created a new VAD project and selecte an existng one for the name of the project. It then, of course, asked you if I wanted to replace the old project. Well it correctly replaced the .vaproj file, but since the other files and directories were still there then the old project right back up! Only the global settings had changed to the default ones (since the .vadproj file was recreated).
