we have a check box that that we created in crm 4.0 for customer that either stopped support with us, or fell behind on support, and that notifies our support and other departments as such. its, a simple enough pop up that come up, and states, "do not support".
It works fine in CRM 4.0 with IE9, IE10 and IE11.
we are currently working on migrating to CRM 2011, and for some reason, this still works with IE9, but stopped working with IE10 and IE11.
Seems kind of weird...
