I'm running Windows 7, Parallels Desktop 7.0.14924 on a MacBook Pro running Snow Leopard (OS 10.6.8). For a while now, when I start Windows, I get a message to the effect that the CD/DVD drive is not found/available. Today I wanted to install a Windows program from a DVD and in fact, Windows is not seeing the DVD. I don't remember when this started, possibly after the upgrade to Parallels Desktop 7. Question is, how do I fix it? Thank you in advance,
