[ZendTo] Re: Upload stalls and connection resets

[Jules]

<rant subject="buggy browsers"> :-)

Make sure you are running on a 64-bit OS for starters, and running a 
64-bit browser (i.e. *not* the standard IE9 in Windows 7 x64 but the 
64-bit version that you can't make your default browser for some utterly 
braindead reason) if at all possible. IE9 64-bit does the job pretty 
well, as does Chrome.

And yes, Firefox isn't good enough.

Unfortunately, uploads over 2GB isn't a feature a lot of users make a 
fuss about, so the vendors can't be arsed to fix the horribly buggy 
upload code they use.

In short, use a better browser. Sorry if that doesn't help when you've 
got several thousand managed desktops all using 32-bit IE7 or something 
like that. :-(

There really isn't a lot I can do about this, other than resort to Flash 
(yuck! I'm not doing that) for the upload process. Sorry there's no 
better news.

It works beautifully on a Mac, as the apps are properly 64-bit as well 
as the OS.
