Craig / slip - I do pretty much the same routine as you, including fairly frequent "disk cleanup" and "defrag" routines. I swear by it too. If I get any flukiness on my computers I cleanup and defrag right away. Could be anything / any server or router in between you and the destination. Could be the receiving end too! John S. - if you're not doing the 'slipknot' routine already its worth it. Now if only I could catch a salmon like John S.!
