Since upgrading to ML 9.3 our kit products do not work properly. When I go to edit them, 90% of the time the options do not fully load so that I can edit them. Sometimes I have to retry up to 15 times (resetting cache, etc) before I can see all of the options on each group in the kit. This never occurred in version 7 or 8 with these exact same products. Tech support has been no help--they suggested this fix, which did not work:

Accessing kits that are large can cause issues due to the number of form posts (a Microsoft issue). Please try raising the value for: add key="aspnet:MaxHttpCollectionKeys" value="2000"

Here is an product example on our site: http://www.bestfriendsstudios.com/p-...ss-labels.aspx

Can anyone help? I've been going crazy & need to add new products but can't because it's nearly impossible to edit the kit products. Thanks.
