Ok, folks, this has me stumped. I have 2 G5s. My older one that I've had for 2 years will not allow me to upload photos or videos to Facebook, Youtube and other sites. Safari or Firefox, it doesn't matter. It simply freezes or times out.

I've confirmed it is not my ISP; I can upload via my other mac. My upload speed is just fine. The sample picture is only 2 meg and shouldn't be an issue. I've turned off my firewall too.

Should I try to replace my Java files? I've checked my updates and they are all current. Not sure where to go to next.

Please help if you have any suggestions.
(OS X Snow Leopard, G5 Intel, 1 Gig RAM, DLS wireless or wired, don't matter).
