Re: Memory Leak

Thanks for the response Vladimir,

To answer your question, yes the PC is connected to the internet, and it is behind a firewall. I also use McAfee's Online Virus Protection service, and conducted a full scan of the PC a couple of days ago, which turned up no viruses/worms, etc. I'm still looking into the issue.

I'll probably be getting a new system this week, and once that is up and running, will reformat and reinstall the system on my current PC.

Thanks again.

Lance
