>I used to listen to Internet radio (XM) and watch tv news on this computer (Windows 7 64-bit 4 GB). But I was not doing any kind of development on this PC. Now I moved all my development to this PC (mostly VFP 9). Do you think that using Internet radio or tv on this PC will slow down the VFP 9 or could cause some adverse effects? TIA.

I do it all the time. Doesn't seem to make a performance issue.

FWIW 4 Gig RAM on a 64 bit machine is fairly marginal. I'd add more if possible. 64bit thrives on memory.
