The symptoms are not exactly what I have experienced but CW2K does not play well with the version of JRE that XP comes with.
I copied the following off of Cisco's Web site.
"The recommended browser is Microsoft Internet Explorer 6.0 (JVM 5.0.0.3805). There are some issues with IE 6.0 Service Pack 1, so be sure to check them. Also, IE 5.5SP2 (JVM 5.0.0.3802) is supported in CiscoWorks Common Management Foundation (CMF) 2.1 and CiscoWorks RMEv3.4. Make sure the Microsoft VM (Java Virtual Machine) is installed.
CiscoWorks uses JRE Version 1.3.1 only. "
This is just one spot. I am still looking for an avenue to upgrade CW2K so that it will play nice with newer versions of JRE.
For any "NON XP" devices you can just uninstall the JRE 1.4.? version and it should work fine. I don't know if you can unistall the JRE version on XP or not. Look in add/remove programs to see if it is possible.
Hope this helps
