It's come to our attention that SlideDeck and IE11 aren't playing well together. We need to accommodate for changes to IE11 in both our detection and handling of the browser, due to more support in areas where the previous versions of IE were lacking.
We have a beta solution that we'll be releasing very soon in an official plugin update, but right now we're testing it with users that request it. If you'd like to get your hands on the fix early, please open a support ticket, and we'll provide it to you.
Thanks for your patience!
UPDATE: SlideDeck 2 has been updated to be compatible with IE11. Please update/renew your product now in order to get the updates. Click Here for a full changelog.
