Designer Control automaticaly opens its Preview Window

Question

Hey Guys
I am having a problem and hope you can help to fix it up
Here is the code i use to open a new Report Using RDC XI with VB6
Set m_Report = Nothing
Set m_Report = m_Application.NewReport
CRDesignerCtrl1.ReportObject = m_Report
The Above Statements work fine when New Report is created for the first time.
The Problem is at run time, when i create another new Report (Using Statements above mentioned) Designer Control automaticaly opens its Preview Window tab "Main Report Preview".
As I am using My own Viewrer Control, I don't want this Tab to be opened. I have searched a lot but yet to find any help
Kindly let me know what can i do TO NOT LET IT OPEN
Your Cooperation will be very much appreciated!

Thank Ludek for your responce..
Let me explain code
Referecnes Added:
Crystal Reports Active X Designer Design And Run-Time Library 11.5
Embedable Crystal report Designer Control libaray 11.5
Crystal Active X Report viewere Library 11.5
Code
Dim m_Application As New CRAXDDRT.Application
Dim m_Report As CRAXDDRT.Report
' Code Executed for new Report Button
Set m_Report = Nothing
Set m_Report = m_Application.NewReport
CRDesignerCtrl1.ReportObject = m_Report
'  Set the report source.
CRViewer1.ReportSource = m_Report
'  Set the viewer to view the report.
CRViewer1.ViewReport
CRViewer1.Zoom 1
When this code is executed for the 1st time (If i click New Report Button) It works fine. but if I click New Report button again  "Main Report Preview" tab of Embedable Designer Controls opens automatically. This tab is opened precisely for execution of this statement
CRDesignerCtrl1.ReportObject = m_Report
More to add, if i click New Report Button again, it raises error "Index out of range".
If hope this explain my situation, if there is anything else, let me know.
Your help will very much be appreciated!
