Applet saving dll files

Question

we have an applet which uses native components (dll) via jni. its a secure signed applet and accesses the cilients local file system and writes the needed dll to users temp folder on load.
we do that with policy settigs
                   Policy.setPolicy(new Policy() {
               public PermissionCollection getPermissions(CodeSource codesource){
                    Permissions perms = new Permissions();
                    perms.add(new AllPermission());
                    return (perms);
               public void refresh(){
          });while applet is running you can not delete the dll (locked file) which was writtnen by the applet (which is a good thing)
I guess because of the recent windows security updates (or sun changed something) we now can not write the dll file directly. we somehow achieve it by writing it as a temp file:
if we use File.createTempFile("wrapper", ".dll",new File (tempFolder)) we can write it as a temp file which is a strange thing.
and now while the applet is running, the temp file can be deleted.
Can any one tell me about the changes that was made by microsoft or sun which causes these differences.

hi, do do you know some url where I get information
about how to make an applet for uploading files by
drag and drop?
thanksI would assume you can search the net to find such a URL better than anyone else here could, since you supposedly know more details about what you're looking for. I won't even bother to write a sample Google search URL - you can do that. Use your brain a little.
