Download issue after upgrade HELP

[medragon]

my site is www.beadedpatterns.com

When someone purchases a download, then comes back to the site to download it, when they click on the download button, it closes IE.

These are all simple pdf files with the largest being 3mg.

This is only happening to some of the customers, not all.
Some using IE get it just fine and others don't.

I moved to a new host, then upgraded to the newest Zen v1.3.9h.
I added SSL to the site, and password protected my downloads file.
Something in all of these changes has caused this to happen.
But because of all the changes, I don't know where to look.

Any Help would be great.

I was just informed by one of the customers that had IE close on them durring download.
That when they went to my Free Patterns page:
http://www.beadedpatterns.com/index....x&cPath=26_482

That it would allow them to download a few patterns and then would close on them again.

Any guesses as to what is causing this?

Can you reproduce this?

Try and see if there are any error messages ot not

[medragon]

It works just fine when I do it.
It works just fine for about half of my customers.
But it is getting really old, having to email people their downloads.
Could it be something with my server?
Because the free patterns page doesn't go through the shopping cart.

Poll them as to if they are on a broadband connection or dial up?

Dial up will probably time out - - if that is the issue
But as you can not replicate it you might never know for certain

[medragon]

It is possible that those costomers could be timing out.
If that was the case, where would I look to fix that?
