Normally, when an HTML file contains two links, the first and second links open within the same window.
Code Used (example):
<A href="http://www.citrix.com" Target="window_new">Citrix<;/A>
<A href="http://www.ufs.nl" Target="window_new">UF Solutions</A>
Running the above code in an ICA session in a fixed or seamless window or an RDP session as an initial program breaks this behavior. Every link opens a new window instead of remaining within the first window.
Affected Versions of IE:
Internet Explorer 4.0
Internet Explorer 5.0
Internet Explorer 5.5
Internet Explorer 6.0
The case is explained in Microsoft article Q321477.
