I have multiple pages with java applet written with SWT. The problem is, applet loads only on first page, to load it on another page i need restart browser, otherwise i get following error:

Exception in thread "Thread-27" java.lang.UnsatisfiedLinkError: Could not load SWT library. Reasons: 
    no swt-win32-3650 in java.library.path
    no swt-win32 in java.library.path
    Native Library C:\Documents and Settings\xxx\Local Settings\Temp\swtlib-32\swt-win32-3650.dll already loaded in another classloader
    C:\Documents and Settings\xxx\Local Settings\Temp\swtlib-32\swt-win32.dll: %1 is not a valid Win32 application

I wonder, how can I unload swt dlls when browser page with applet is closed?
