I had a weird problem when I tried to open an Excel 2007 file. It loaded then flashed on and off. When I looked in the Task Manager I had multiple copies of it open. Wondering if I had a virus. I tried to use Housecall but got a message about Java Runtime Environment being disabled so I tried to download the correct environment and got an error "Several Java Virtual Machines running in the same process caused an error" This don't look good? Anyone have any ideas please?
