Depending on your usage scenario, the GP Home Page can be the greatest thing since sliced bread or a bit of a resource hog. If you don't use Outlook or don't have Outlook open, it can be really slow.
So what do you do if you don't want the home page to show every time you load GP? Easy:
1) click customize this page
2) Uncheck Display home page when Microsoft Dynamics GP Starts
That's it!
