browser freezing while applet is loading

I have a web page with several MarvinView applets.


When I open the page in Internet Explorer and I look another window while applets are loading, they freeze the browser. If I wait the finishing of the applet loading, IE and applets work fine.





Here is the JavaScript code from one of the applets. (The others' code are similar.)

Code:

<script LANGUAGE="JavaScript1.1" src="marvin/marvin.js"></script> <script LANGUAGE="JavaScript1.1"> <!-- try {     mview_name="Struc_5";     mview_begin("marvin/", "125", "125");     mview_param("rows", "1");     mview_param("cols", "1");     mview_param("bgcolor", "#FFFFFF");     mview_param("cell0", "|Fc1ccc(C(=O)c2ccccc2)c(F)c1");     mview_param("preload", "MolExport,SmilesExport,GraphInvariants,Parity");     mview_end(); } catch(er) { } //--> </script>

Can anyone help me?

You should delete the try - catch blocks from your JavaScript code. It seems that try - catch blocks does not permit displaying signed applet certification window if the applet's window is not in the focus.


Normally, the certification window should pop-up. It hangs on the browser running until you submit it.


Thus, modify your code like this:

Code:

<script LANGUAGE="JavaScript1.1" src="marvin/marvin.js"></script> <script LANGUAGE="JavaScript1.1"> <!--     mview_name="Struc_5";     mview_begin("marvin/", "125", "125");     mview_param("rows", "1");     mview_param("cols", "1");     mview_param("bgcolor", "#FFFFFF");     mview_param("cell0", "|Fc1ccc(C(=O)c2ccccc2)c(F)c1");     mview_param("preload", "MolExport,SmilesExport,GraphInvariants,Parity");     mview_end(); //--> </script>
