I have a custom module that uses some javascript to open another window.  This window causes parent window to loose user authentication and refresh and close to root of portal.  Any clues as to why?

<script language="javascript">
function launchLog(strFid){
 var strBar = 'directories=no,location=no,menubar=no,titlebar=no,toolbar=no,scrollbars=yes,width=800,height=600,resizable=yes';
 var strLoc = 'https://mySite/DesktopModules/Wrallp.fileManager/viewFileLog.aspx?pid=445&fil=0&fid=' + strFid;
 var winEdit = open(strLoc,'FileActionLog',strBar);
 }
</script>

Need is urgent.  Post is old and was in extend-it sub.

Thanks for the response mike.

The site has ad authentication enabled but will kick off a dnn authenticated user as well.  I tried with http with no change in behavior.  Window opens from Javascript call, close child window, click on parent and anyone is logged off and brought to home page.

Allow me to rephrase this:  I have a custom module.  That module needs to be open with two parameters set prior to being open.  The way that I have done this is to create "pages" via the "add" in the page functions.  At the bottom it allow you to link to page within site or "external resource"  I have to select external resource as I have parameters that I need to pass via querystring of response.  So I enter entire url.  https://mysite/myportal/home/tabid/7389/fd/712/default.aspx.  This link works perfectly but if I use the javascript to open a child (or even an anchor) the problem described in the original post happens when the parent is subsequently clicked.

Is there a better way to open a page on a portal with an additional parameter?

 Site is a 4.8.2 upgrade

Glad you got it sorted out Steve.
