Steps to Reproduce Behavior

Create a new Standard EXE project. Form1 is created by default.
Add a new UserControl from the Project menu. Set the BackStyle property to Transparent and the Windowless property to True.

Place a Shape control on the UserControl, then add the following code to the UserControl's code window:

      Private Sub UserControl_Initialize()
         Shape1.BackStyle = 1 'Opaque
         Shape1.Shape = 2 'Oval
      End Sub

      Private Sub UserControl_Resize()
         Shape1.Move 0, 0, UserControl.Width, UserControl.Height
      End Sub

Close the UserControl designer.
Add a Frame control to Form1.
Add your UserControl to Frame1.
Press the F5 key to run the program and note that the border and caption of the frame control disappear.
