VBA Internet Explorer will not follow hyperlink

    Question

  •  

    Hi,

     

    I am using Internet Explorer 6 and Access 2003 VBA.

     

    IE is starting up OK but when the program asks IE to go to another web site the IE session "flashes"

    as if the hyperlink is being followed but the display does not change. Also the code routine returns true in that it can

    find the hyperlink text.

    This hyperlink is  like  "/website2/listScripts.do". The first website is like https:///website1.

    The relevant html of website1 is:

    <a class='navbarIndentedLink' onmouseover='window.status="";return true' href='/website2/listScripts.do>Scripts</a>

     

    The strange thing is that the code seems to work OK with other websites.

    If I change the code so it goes to www.google.com and ask it to follow the hyperlink for "maps" it works correctly.

     

    So it seems that VBA cannot process the link.

    The link works correctly when done manually.

     

    Can someone see how I can fix the problem?

     

    Code is attached.
