Take a look at my screenshot:

Click here for screenshot

Form2.vb can be viewed in code or in form designer mode, which is fine. The button for view form shows up in Solution Explorer

Form1.vb can only viewed in code, and the icon is different to Form2.vb (as you can see in the screenshot). And there is no button in Solution Explorer to show the form.

How can I make it show the form designer for Form1.vb again?
