Based on what you've posted my best estimate of what's happening is that the users in question are launch the TSM Web Client (not the Web Admin) which requires a Java 2 plug-in. Once the plug-in is downloaded and installed there are likely some older Java applets that don't work with the plug-in. Case in point is the command line applet in the Web Admin. So to switch between the two you have to alter the browser settings so do de-select the Java 2 plug-in when you want to run an applet that does not like Java 2.
