Bridge batch processing script for Photoshop stops after ten mins

Question

I have a javacript to help batch process collections of images in Bridge by sending them (in layers) to Photoshop CS5. It works perfectly, except it stops running after about ten minutes (around 6-10 images) so that I have to keep restarting the script. This behaviour has only started since the script was installed in the Bridge startup folder so that it could be started from the (right click) menu. The script does not seem to time out when run via ExtendToolkit.
Does anyone know why this is happening?

Thanks again Paul. Can I ask you where the best place to insert that would be? The script is below - I'm sure you'll recognise it :6).
I've also been wondering if its possible to alter the script so that the files in bridge are opened in PS as Smart Objects (in layers)? There is a script 'Open as Smart Object in Layers' but I haven't been able integrate it into your fantastic script.
#target bridge
if( BridgeTalk.appName == "bridge" ) {
processDocs = new MenuElement("command", "Process selected docs", "at the end of Thumbnail");
processDocs.onSelect = function () {
var sels = app.document.selections;
var selectedFiles = new Array();
for(var a in sels){
    selectedFiles.push(sels[a].spec);
      if(selectedFiles.length> 1){
           var bt = new BridgeTalk;
           bt.target = "photoshop";
           var myScript = ("var ftn = " + psRemote.toSource() + "; ftn("+selectedFiles.toSource()+");");
           bt.body = myScript;
           bt.send(5);
function psRemote(selectedFiles){
app.bringToFront();
for(var f in selectedFiles){
var thisDoc = open(File(selectedFiles[f]));
/*run an action if required */
/* app.doAction("atn", "atnSet"); */
/*script listener code goes here...
  You will need to remove the //===== lines or the script will fail 
/* end script listener code */
      var saveFile = new File('~/desktop/'+(new Date().getTime().toString())+'.psd');
      app.activeDocument.saveAs(saveFile);
      app.activeDocument.close(SaveOptions.DONOTSAVECHANGES);
