How do I update my forms to show changes in my database?

I feel like this should be easy but I can't figure it out.

Following the tutorials included with VB 2005 Express, I have created a MDI application that has one form in which I dragged over all the detail view fields of a small database.

If I only open one instance of the form everything is great. I can change the data and save it and it's great.

But if I open a second instance of the form and change the data and then go back to the first instance of the form, it doesn't show the altered data. I visually checked the database and it has the new data but the first instance of the form still shows the old data. This is a major problem for what I want to do.

How do I get my forms to update their data to immediately reflect the real changes in the database I need all views to get as close to real time data as possible.

Any help would be greatly appreciated...
