Steps to Reproduce Behavior

1. Create a Form.



2. Add a Microsoft Web Browser Control to the form and set its properties as follows:

   
      Name: WBCtrl1
      Refresh: NODEFAULT
      Init: This.Navigate("www.microsoft.com") 




3. Add a TextBox to the Form. The TextBox will be used to enter the URLs you want to connect to. Add the following code to the Valid event of this TextBox:

   
         IF !EMPTY(This.Value)
            ThisForm.WBCtrl1.Navigate(This.Value)
         ENDIF 




4. Run the form, type a valid URL into the TexBox, and then hit the ENTER key to go to and display the URL. Note that repeating step 4 several times may cause Visual FoxPro to crash.
