For VS.NET users, the cmd.exe that appears during install is a hack. It will go away later.
Initial settings for options are taken from VA.NET and/or VA 6.0. Do not remove the latter until VA X is installed. Actually, keep the latter. You can remove VA X using the Add/Remove Software CP and reactivate VA.NET or VA 6.0 using "Tools|Add-in Manager" or "Tools|Customize|Add-ins".
You need a valid VA.NET or VA 6.0 key to run VA X in the respective IDE. There is no trial mode.
We have noticed the background of the icons in the Context and Definition field is dark sometimes. We are working on this one.
Browse the options dialog. It's your only source of documentation.
Make sure you check out what we currently call the "VA View". See if you can figure out what it does.
