I just wanted to let you know that McAfee virus scan and I have come to a complete parting of ways and things seem to be going much better with ISE. Apparently unloading and/or disabling McAfee doesn't really get rid of all components. I'm using a trial version of another virus product, AVG, and have rebuilt an entire setup with ISE 3.5, working for about 10 minutes without a single access violation!

If I'm lucky, this will take care of the screen "echos" as well. Thanks for the suggestion. It prompted me to take a second look!
