Permission denied error in Javascript

[Tanmaya Kulkarni]

Hi,

I my web application, am using frames.

<frameset name="aaframe" rows="190px,64.0%,45px" >
<frame name="aframe" language="vb" src="../Top_page.aspx"
frameBorder="0" noResize scrolling="no">
<frameset name="bframe" cols="25%,75%">
<frame name="rleft" src="../Aspx/Left_page.aspx">
<frame name="rright" src="../Aspx/Right_Page.aspx">
</frameset>
<frame name="cframe" language="vb" src="../bottom_page.htm"
frameBorder="0" noResize scrolling="no">
</frameset>
Now, in Right Page when user presses on a button called "FullScreen", I
change percentage of aaframe rows to "0%, * ,0%" by following code.
function showFullScreen()

{

if (document.Form1.Image_FullScreen.title ==
"Switch to Full Screen")

{

parent.aaframe.rows = "0%,*,0%";

parent.bframe.cols = "25%,75%";

document.Form1.Image_FullScreen.title="Switch
to Normal Screen";

document.Form1.Image_FullScreen.src="normalscreen. jpg"

}

else

{

parent.aaframe.rows =
"190px,64.0%,45px";

parent.bframe.cols = "25%,75%";

document.Form1.Image_FullScreen.title="Switch
to Full Screen";

document.Form1.Image_FullScreen.src="fullscreen.jp g"

}

}

This maximises my page. The code works fine when the page loads for the
first time.

When the page reloads after some click event, I get a javascript error
"Permission Denied".

Can anyone hlpe me out whats the issue?

Thanks,

Tanmaya
