You'll notice that I didn't specify which finger, you thought of that all on your own. But if you're dying to give MS some feedback, don't use one finger, use all ten. Go here to give product improvement suggestions for MS Dynamics GP. This link ultimately leads to connect.microsoft.com where you can give product improvement suggestions on Dynamics GP and lots of other Microsoft products. You can also vote on other people's suggestions.
If see an area where Dynamics GP needs some improvement, don't give MS the finger, give them all ten and lets see if we can make a difference.
