TS Web Access options button is refreshing the screen possible jscript issue

Hello,

I am using TS Web Access installed on a 2008 Terminal Server R1 and the options button is not working correctly, and i think the problem is in the HTMl or jscript code attached.  What is happening is when you click on the "Options" button the options become visable as they should, but after about a second the page refreshes and they are re-hidden.

Any help would be greatly appreciated.

cheers,

Tony

function hideshowOptions(){
                    if (document.getElementById("opt_panel").style.visibility == "hidden") {
                        document.getElementById("opt_panel").style.visibility = "visible";
                        document.getElementById("ButtonOptions").innerHTML = "<u>O</u>ptions" +" &lt;&lt;";
                    }
                    else {
                        document.getElementById("opt_panel").style.visibility = "hidden";
                        document.getElementById("ButtonOptions").innerHTML = "<u>O</u>ptions" +" &gt;&gt;";
                    }
                }
                var myExp = new Array(7);
                var myAr
                myAr = new Array
