You haven't told us the specs for your machine Sandra but I agree with Mike, a new Win 7 multicore machine with lots of ram doesn't seem to have those problems we used to get with XP. I have everything running including AV on my AMD Phenom and haven't had any glitches or dropouts yet. That even includes having several browers windows open too. I used to make sure the browser was closed but even that doesn't seem to bother my new setup.
The only problem I found is I can't format a floppy disc using my USB external A drive for my Korg keyboard. After some Google searches I found out the problem is only on AMD machines using a Gigabit motherboard and that's exactly what I have. I have to run a USB cable from my Korg to the machine to transfer stuff or use my laptop.
