AbleCommerce Shopping Cart Software

Hi, whenever I go through the error log I see hundreds of "Invalid Viewstate" Errors. I can't replicate the errors myself, but I would like to turn off/limit the viewstate. I tried putting a directive in web.config and _VIEWSTATE still shows up. I tried turning it off per page and it still shows up. I suspect that ablecommerce is turning it on somewhere.

When I looked it up online, I read the following:
"I've seen this error caused by the combination of good sized viewstate and over aggressive content-filtering devices/firewalls (especially when dealing with K-12 Educational institutions). "

Our website sells educational products so it is very important that we solve this. Any help would be appreciated.

Thank you in advance.

It also happens if you do something like click a button before full page load. I have had it happen in the admin in options when a product had a log of choices and I got impatient when I was sorting them and didn't wait for full page load.

Thanks for the reply, but that doesn't seem to be the problem. I have tried constant clicking and I just can't seem to replicate the problem. I really need to turn this off! or maybe lower it somehow.
