OnCommand System Manager 3.1.1 does not exit

I have got 3.1.1RC1 installed - every time I start it it starts a java.exe process but the java process does not exit when I close the browser. I have to go to task manager and kill it by hand. If I don't do this I eventually have a number of java procs using 65 - 85 MB each which impacts performance.

Is this fixed in a more current version?
