This fix does not always work as the clicked link may be a sub component of the
current one with focus, for example if it is in an IFrame.

Here is the fix that will account for frames or iframes:

1) Add next two methods to the "#region Public Method Members" of csEXWB.cs 
file 

        /// <summary>
        /// Calls click method of active element
        /// </summary>
        public void ClickActiveElement()
        {
            IHTMLElement elem = this.GetActiveElement();
            if (elem != null)
                elem.click();
        } 

        /// <summary>
        /// Attempts to return active IHTMLElement interface instance
        /// Accounts for Frames and Iframes
        /// </summary>
        /// <returns></returns>
        public IHTMLElement GetActiveElement()
        {
            IHTMLElement elem = null;
            string tagname = string.Empty;
            IHTMLDocument2 doc2 = GetActiveDocument();
            if (doc2 != null)
                elem = doc2.activeElement;
            if( (elem != null) && (!string.IsNullOrEmpty(elem.tagName)) )
                tagname = elem.tagName.ToLower();
            while ((!string.IsNullOrEmpty(elem.tagName)) &&
                ((tagname == "frame") || (tagname == "iframe")))
            {
                //Cast it to IWebBrowser2
                IWebBrowser2 pwb = elem as IWebBrowser2;
                if (pwb != null)
                {
                    //Now get the document
                    //If you attempt to access the document via 
IHTMLFrameBase2.contentWindow
                    //you will get a "Access Denied" exception
                    IHTMLDocument2 pdoc2 = pwb.Document as IHTMLDocument2;
                    if (pdoc2 != null)
                        elem = pdoc2.activeElement;
                    if ((elem != null) && (!string.IsNullOrEmpty(elem.tagName)))
                        tagname = elem.tagName.ToLower();
                    else
                        tagname = string.Empty;
                }
            }
            return elem;
        }

2) In "case WindowsMessages.WM_LBUTTONUP:" of WndProc method of IEServerWindow 
class 
(csEXWB.cs) change 

                    if (!browser.m_InternalHasFocus) 
                    { 
                        browser.Focus(); 
                    } 
To: 

                    if (!browser.m_InternalHasFocus) 
                    { 
                        browser.Focus(); 
                        browser.ClickActiveElement(); 
                    } 

This issue was resolved in V2.0.0.1

Regards,

MH
