I have been finding that some of the pages will refresh as soon as I "X" the extract box and I can continue with downloads. Then there are other pages where you "X" out the download page, then have to click on "back" and wait for the page to reappear. It is like using dial up internet when I am paying for high speed satellite internet.
It would make sense to have all pages refresh when the "X" on the extract page is clicked, to facilitate faster downloads. The longer a person has to sit on the site waiting, the longer others have to wait also. I have contacted technical support on this and will add to this post whenever they contact me with an answer.
If anyone else has this problem, it would be interesting to hear about it.
