One last question....

Tableau 2 navigation menu works fine in edge & safari but I have found an issue with ie11. The menu (top right) won't pull out the side menu (categories & links) if the page is reduced to smaller resolutions. It simply causes the screen to darken and puts an X in the top right to close the menu. So in my opinion it tries to go but fails.

I have installed fresh copies on to Zen Cart v1.5.5f with Tableau 2 v2 through to v2.1.0.6 and this issue is present always. It's not causing any errors in the logs or the developers tool kit in ie11 (or edge)...….

Any ideas?
