RD, This fixed my problems. I updated my Java to 1.6.2 from 1.6.1 and noticed 1.6.1 stayed on my computer after the update and a few little funky things started happening. I went to Add/Remove Programs and deleted 1.6.1 and then Defragged and now shes running like a top. So try removing all versions of Java and then dn/ld the version that was suggested above. Hope this helps.
Something else you might take a look at to clean your system after deleting programs is
CCleaner.com.
