Yea, it does that to me.
When you click to download, watch the bottom of the screen to see if any writing comes up i.e. http://.....download... If it doesn't, press refresh or F5.
Or if that doesn't work, when it says action cancelled - press back and let it reload. Try it a few times - that always works for me
