This is not a Microsoft bashing blog, so when the folks from Redmond put out something good we are all over it. If you haven’t had a chance to use Microsoft SharedView, you might want to try it out. It is a free application but it is still in beta. Recently I have been working on a project where I need to collaborate with a buddy of mine in San Diego. We have been using SharedView to work together on his Vista PC, but I was unable to share my XP box with him. My screen would be gray instead of showing my desktop. Turns out the problem has to do with my Nvidia video card and hardware acceleration. Here is how to fix the problem:
Click on Start menu > Control Panel > Display > Settings > Advanced > Troubleshoot > Move the slider to "None" to disable hardware acceleration
