Download Problems

[Rebecca J. Hoffman]

I have an 800 MHz iBook. I'm trying to download the latest version of 
iMovie. I keep losing my internet connection. I turned off the "sleep" 
function in System Prefs, thinking that was the problem, but that 
didn't help. I've had this happen before on large downloads. Any 
suggestions?

Here's the second question. When I was using Omniweb, if I lost my 
connection during a download, when I dialed up again the download took 
up where it had stopped; I didn't lose what I had already gotten. Now 
I'm using Safari, which doesn't seem to have the same feature. When I 
dial up, the download goes nowhere and the only option seems to be 
starting over. I have over half of iMovie downloaded (for the second or 
third time) and I'd love to be able to take up where I left off. Any 
suggestions for this problem?

Thanks!
Rebecca
