Do you have to use Internet Explorer? I wrote an
Java Application, where the customers can show documents with different applications (e.g.
Word or Excel) I start those applications in the same way like you. The only difference is, that I start executables. They appear always on top.
So my question to you, can you use a different browser (Netscape, Mozilla, Opera ...). Those browsers are executables and I'm shure, they will be on top.
