You can use a Javascript function as a bridge between the 2 frames.
[main HTML (a.html)]
<HTML><HEAD></HEAD>
<FRAMESET COLS="50%,*">
<FRAME SRC="f1.html" NAME="f1" >
<FRAME SRC="f2.html" NAME="f2">
</FRAMESET>
</HEAD>
[frame 1 HTML (f1.html)]
<HTML><HEAD>
<SCRIPT>
function toOtherFrame(a, target) {
if (target == "f1")
parent.f1.document.app1.fromOtherFrame(a);
else
parent.f2.document.app2.fromOtherFrame(a);
}
</SCRIPT>
</HEAD>
<BODY>
<APPLET CODE="app.class"
NAME="app1" MAYSCRIPT
HEIGHT=200

<PARAM NAME="target"
