When I drag a ComboBox control on my form, I click it and select the DataSource property.

Then I click the add new datasource link in the bottom.

And SQL connection windows pops up asking me to choose a connection.

Here's where the program takes a dump on my face:

I click "New Connection" and instead of the New Connection form opening up, I'm tossed back to my form.

How can I fix this? I'm using Visual C# 2008 Express Edition

I don't mind helping you with homework but abide by the rules. If you're aspiring to be a software developer then you must take notice that the two connection dialogs are the exact same and the problem isn't related to what component invokes the dialog, but the dialog itself.
