That happens to a guy at work all the time and drive him bonkers when it does that. Of course he always keep his stuff on the A drive and I keep telling him to move it to the hard drive first. I would do like Slynky said and open up 5 or 6 files and SAVE them till it goes away then always move your work to the hard drive before you work on it. Why work off the A drive anyways its slower than snot.
