running Alfresco 3.2 EE on vista with tomcat from zip. It generally works well, but occasionally can not shut down the server. 

ctrl-c in the window and try to close the window with tomcat but no go, cannot close the window.  No error messages apparent in tomcat log. 

also cannot shut down machine, cpu usage shoots up to around 100%, mouse movement becomes difficult

have to hit the power button to shut down.

Anyone else have this problem?  Any suggestions to resolve?

it seems to only occur on a laptop I have that is not connected to the internet.  Rather than hitting the power switch, I found that plugging in a USB wireless DSL connection and connecting to the internet with it will shut down the tomcat.  So it seems to be some type of issue with networking on a PC.   

The problem doesn't occur on a networked pc I also use.
