AxWebBrowser.En dInit() causes delay !

[Lecture Snoddddgrass]

Hi,

I noticed that my WinForms app was taking a while to start up. I stepped
through the code to find out which line was causing the delay. The delay is
occurring within one of my UserControls whose designer-generated
InitializeCompo nent() method instantiates a web browser control and
eventually calls EndInit() on it. It's that EndInit() call that takes
several seconds to complete.

What's odd is that my application makes extensive use of this particular
UserControl with the embedded web browser, but only the FIRST call to
AxWebBrowser.En dInit() causes the delay. If the user subsequently causes
more of these custom UserControls to be created, the AxWebBrowser.En dInit()
calls are completed immediately. There is no delay at all.

How can I avoid the delay on the initial call to AxWebBrowser.En dInit()?
For completeness, the InitializeCompo nent() code of my custom user control
looks like this:

** Note that the name of the class is WelcomeControl and the name of the
WebBrowser control is 'WB'.

private void InitializeCompo nent(){
System.Resource s.ResourceManag er resources = new
System.Resource s.ResourceManag er(typeof(Welco meControl));
this.WB = new AxSHDocVw.AxWeb Browser();
((System.Compon entModel.ISuppo rtInitialize)(t his.WB)).BeginI nit();
this.SuspendLay out();
//
// WB
//
this.WB.Dock = System.Windows. Forms.DockStyle .Fill;
this.WB.Enabled = true;
this.WB.Locatio n = new System.Drawing. Point(0, 0);
this.WB.OcxStat e =
((System.Window s.Forms.AxHost. State)(resource s.GetObject("WB .OcxState")));
this.WB.Size = new System.Drawing. Size(312, 280);
this.WB.TabInde x = 0;
//
// WelcomeControl
//
this.Controls.A dd(this.WB);
this.Name = "WelcomeControl ";
this.Size = new System.Drawing. Size(312, 280);
((System.Compon entModel.ISuppo rtInitialize)(t his.WB)).EndIni t();
this.ResumeLayo ut(false);

}

Thanks,
